1. Humans exhale carbon dioxide.
2. The photosynthesis not being circulated will unbalance the oxygen levels.
5. Phosphorus erodes into the ground and is then absorbed by plants and animals. The Phosphorus cycle startes in rocks. When it rains, the phosphates and other minerals are removed from the rocks and distributed in soils and the water.
1. What are some human influences on the carbon cycle?
Carbon is present in the human body, in animals, and plants. Carbon is also present in the air (CO2), in the oceans, and in the ground.
2. How might the removal of vegetation affect oxygen levels in atmosphere.
Since Oxygen is a product of Photosynthesis which is what plants do as they take in and use up Carbon di Oxide (CO2) in order to grow. As vegetation was removed there would obviously be a decrease in the amount of Oxygen and an increase of CO2 available in the atmosphere.
3. Identify the role of bacteria in carbon, nitrogen, and phosphorous cycles.
Most of them are decomposers which release the elements from dead material.
In the nitrogen cycle they have the additional roles for :
fixing nitrogen to create nitrate (root nodules and free living)
changing urea and ammonia into nitrates
destroying nitrates and turning them into nitrogen gas
4. Explain the statement that nutrients cycle, but energy flows.
Nutrients are cycled through food chains, while energy is a one-way flow from the sun. You can “recapture” nutrients, but not energy.
5. Summarize the phosphorous cycle.
The phosphorus cycle is one of many mineral nutrient cycles demonstrating the constant cycling of elements through organisms and the environment. The nitrogen cycle and carbon cycle are the two most well known examples of these natural cycles. The phosphorus cycle differs from these other cycles in that it does not have an atmospheric component to the cycle
1) Exhaust from cars, factories, breathing out.
2) It could cause oxygen levels to drop because there wouldn’t be as many plants to transfer carbon into oxygen.
3) The biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
1, The main inluence is burning fossil fuels.
2. As vegetation was removed there would obviously be a decrease in the amount of Oxygen and an increase of CO2 available in the atmosphere.Therefore we would not be able to breathe.
3. They are decomposers which release the elements from dead material.
4. Nutrients are cycled through food chains, while energy is a one-way flow from the sun. You can recapture nutrients, but not energy.
5. The phosphourous cycle is a biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
1.Humans impact the carbon cycle during the combustion of any type of fossil fuel, which may include oil, coal, or natural gas.
1. What are some human influences on the carbon cycle?natural movement of carbon among animals, plants, the soil, the oceans and the atmosphere.
2. How might the removal of vegetation affect oxygen levels in atmosphere.Since Oxygen is a product of Photosynthesis which is what plants do as they take in and use up Carbon di Oxide (CO2) in order to grow
3. Identify the role of bacteria in carbon, nitrogen, and phosphorous cycles.Most of them are decomposers which release the elements from dead material
4. Explain the statement that nutrients cycle, but energy flows.It sounds like it might be particular to your text or class, but in both energy and nutrients, generally the further you get down the cycle/chain/flow
5. Summarize the phosphorous cycle.s one of many mineral nutrient cycles demonstrating the constant cycling of elements through organisms and the environment
1. What are some human influences on the carbon cycle?
Photosynthesis is a complex series of reactions carried out by algae, phytoplankton, and the leaves in plants, which utilize the energy from the sun.
2. How might the removal of vegetation affect oxygen levels in atmosphere.
Since Oxygen is a product of Photosynthesis which is what plants do as they take in and use up Carbon di Oxide (CO2) in order to grow.
3. Identify the role of bacteria in carbon, nitrogen, and phosphorous cycles.
In phosphorus cycle bacteria decomposes dead organisms and also fossils and phosphorus is available in organisms so when bacteria decompose them phosphorus is released
1. We are polluting the air, plants breathe Carbon (in the form of CO2) and produce O2 and animals do the opposite (breathe O2 and exhale CO2), and chopping down certain ecoystems, like rainforests.
2. Since Oxygen is a product of Photosynthesis which is what plants do as they take in and use up Carbon di Oxide (CO2) in order to grow. As vegetation was removed there would obviously be a decrease in the amount of Oxygen and an increase of CO2 available in the atmosphere. Therefore we would not be able to breathe. We would be able to breathe but because of the lack of Oxygen we would breathe heavier and more rapidly. The more the Oxygen is depleted the more rapidly we would breath and the harder it would become for us to stay alive until eventually there would be insufficient Oxygen to sustain life.
3. In the nitrogen cycle, the bacteria uses and transforms the nitrogen so it can be used again. In the carbon cycle, the bacteria breaks down the carbon compounds in dead animals and plants and converts the carbon to CO2 if oxygen is present. In the phosphorus cycle, bacteria decomposes dead organisms and also fossils and phosphorus is available in organisms so when bacteria decompose them phosphorus is released.
1Carbon Cycle: We breathe in oxygen and breathe out carbon dioxide, just like any other living animal.
Nitrogen Cycle: When a human eats any plant, they consume some amount of nitrates, same as any animal. Also, were a human to die and its body allowed to decompose naturally, we would affect it in the same way as any other animal
2 Loss of vegetation would lessen the amount of oxygen in the atmosphere because it consumes carbon dioxide and emits oxygen.

Phosphorus enters the environment from rocks or deposits laid down on the earth many years ago. The phosphate rock is commercially available form is called apatite. Other deposits may be from fossilized bone or bird droppings called guano. Weathering and erosion of rocks gradually releases phosphorus as phosphate ions which are soluble in water. Land plants need phosphate as a fertilizer or nutrient

1.) We burn natural gases which causes more carbon. We also dont bury our dead so that the body can be decomposed and the carbon is absored. This causes the cacarbon to make a layer around the Earth causing global warming
2.) Since vegetation takes in carbon dioxide and breathe out oxygen it keeps the level of oxygen to carbon dioxide to be equal.
4.) The producers get energy from the sun. When the consumer eats the producer it gets energy from the producer which got energy from the sun. This is how to energy flows.
1.) automobiles, spray-on cologne/perfume, and factories.
2.) The oxygen level would decrease because plants produce alot of our oxygen.
3.) Bacteria causes the nitrogen in the nitrogen cycle to be usable.
1. Every organism on Earth needs carbon either for structure, energy, or, as in the case of humans, for both.
2. We would not be able to breathe; although we would kinda of sorta, but we would breathe very heavily an rapidly.
3. Most of all of them are decomposes, which release the elements from dead material.
4. In both energy an nutrients generally the further you get down the cycle, the less energy an nutrients you have.
5. The phosphorus cycle is a sedimentary cycle (unlike carbon, oxygen, and nitrogen), the atmosphere is not a reservoir for phosphorous nor do microorganisms fix phosphorus.
1.) Burning the fossil fuels which has a negative impact on the atmosphere
2.) There would be an decrease in the amount of oxygen and an ncrease of C02 availble in the atmosphere.
3.) Bacteria breaks down the nitrogen into nitrates that can be consumed by plants.
4.) It means electricty.
5.) Phosphorus is an essential nutrient for plants and animals in the form of ions, it also forms parts of important life-sustaining molecules that are very common in the biosphere.
1.) Humans have contributed to an increase in atmospheric carbon dioxide by burning fossil fuels and other organic matter.
2.) Less vegetation remains to absorb carbon dioxide from the atmosphere through photosynthesis when large areas of forest are burned.
5.) The phosphorus cycle is the movement of phosphorus from the environment to organisms and then back to the environment.
1. We are composed of carbon, so when we die, we release our carbon back into the atmosphere.
2. It would cause them to decrease and the amount of carbon-dioxide to increase.
3. It helps break down the carbon of decomposing bodies.
5. The breakdown and release of phosphorus into the atmosphere.
1. What are some human influences on the carbon cycle? Burning of fossil fuels and chopping down trees.
2. How might the removal of vegetation affect oxygen levels in atmosphere. The oxygen levels would go down because plants absorb to carbon dioxide and release oxygen and humans do the same but vice versa so carbon dioxide levels would rise as Oxygen levels would decrease.
3. Identify the role of bacteria in carbon, nitrogen, and phosphorous cycles. To break down organism creating vital components of the cycles in question.
4. Explain the statement that nutrients cycle, but energy flows. Energy flows through the food chain from prey to predator and nutrients cycle between plant and organism (ie if an anteater eats an ant, it gains the nutrients from the ant eaten. If a human eats the anteater the human will gain nutrients from both the ant and the anteater.)
5. Summarize the phosphorous cycle. Inorganic phosphorus is absorbed by plants or animals, which die and decompose which recreates the inorganic phosphorus
1. What are some human influences on the carbon cycle?
-We breathe in oxygen and breathe out carbon dioxide
-Trees breathe in carbon dioxide and breathe out oxygen
-Animals die and carbon moves into the soil.
-The ocean surface absorbs carbon dioxide from the atmosphere
2. How might the removal of vegetation affect oxygen levels in atmosphere.
-There would obviously be a decrease in the amount of Oxygen.
3. Identify the role of bacteria in carbon, nitrogen, and phosphorous cycles.
-Fatories that let off smoke affect and pollute air and affects carbon in the air.
4. Explain the statement that nutrients cycle, but energy flows.
-I dont not understand this question, and I tryed to look it up on google, but couldnt find or understand anything it was saying!
5. Summarize the phosphorous cycle.
-The phosphorus cycle is a sedimentary cycle unlike carbon, oxygen, and nitrogen, the atmosphere is not a reservoir for phosphorous nor do microorganisms fix phosphorus as they do nitrogen. Phosphorus enters the biosphere almost entirely from the soil through absorption by plant roots. Weathering of rocks containing phosphate minerals, chiefly apatite, results in the relatively small pool of inorganic phosphorus available for organismal use. In most soils the major amount of phosphorus absorbed by plants comes from organic molecules that undergo decomposition releasing phosphorus in plant-available inorganic forms. The release of organically bound nutrients to plant-available forms is termed mineralization, a process important in the release to the soil of sulfur and nitrogen as well as phosphorus. Phosphorus is used by organisms in energy transfers, as a component of nucleic acids, and as a structural element of membranes phospholipids.
1. By burning fossil fuels human beings are releasing more carbon into the air, faster than it can be absorbed by plants or the oceans.
2. Since oxygen is a product of photosynthesis which is what plants do as they take in and use up carbon dioxide in order to grow. As vegetation was removed there would obviously a decrease in the amt. of oxy. and increase carbon dioxide.
3. It decomposes dead organisms and also fossils
4. The energy flows through an ecosystem, while nutrients are cycled within an ecosystem.
5. It’s the bio geochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
1.burning fossil fuels, cutting down forests,breathing air
2.it would have a major change in the levels in the atmosphere because vegetation is a great source of oxygen
3.Most of them are decomposers which release the elements from dead material.
4.
1.It is present in the body.
2.If people don’t eat vegetables, they will be less healthy.
3.In the nitrogen cycle, it fixes nitrogen to create nitrate. Carbon cycles are consumed by bacteria, and fixing phosphorous cycles.
4.nutrients go round and round, while energy goes through.
5.It is Phosphorous.
1. Humans burn fossil fuels, which has a negative effect on the cycle. But, humans breath out carbon dioxide which provides for the plants.
2. Oxygen level would drop drastically because plants provide oxygen for the atmosphere.
3. Nutrients go through cycles, which means they go to different stages but end up at the same place they started eventually. Energy flows, because it can never be destroyed, so unlike nutriets which can be, energy continously flows through everything.
1. Humans influence the global carbon cycle in several ways, but primarily through burning fossil fuels
2.As vegetation was removed there would obviously be a decrease in the amount of Oxygen and an increase of CO2 available in the atmosphere.
3.Most of them are decomposers which release the elements from dead material. In the nitrogen cycle they have the additional roles for : fixing nitrogen to create nitrate (root nodules and free living) changing urea and ammonia into nitrates destroying nitrates and turning them into nitrogen gas
4.In the flow of energy and inorganic nutrients through the ecosystem, a few generalizations can be made: 1. The ultimate source of energy is the sun 2. The ultimate fate of energy in ecosystems is for it to be lost as heat. 3. Energy and nutrients are passed from organism to organism through the food chain as one organism eats another.
5.The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth. The production of phosphine gas occurs only in specialized, local conditions.
2. Vegetation takes carbon and then turns it back into oxygen.
4. Nutrients go through food chains but, energy comes from the sun.
5. A mineral nutrient cycle
1. Humans exhale carbon.
2. It would decrease oxygen because vegetation produces oxygen.
3. Bacteria breaks down animals in the carbon to absorb carbon, and changes nitrogen into a usable gas in the nitrogen cycle. In the phosphorous cycle, bacteria breaks down animals to release phosphur.
4. Nutrients pass through each eater again and again, but energy decreases each time from each transfer.
5. Phosphate is released from the earth into the sea, the phosphate forms insoluble deposits and then is transferred back into the earth and the cycle begins again.
1. we breathe one carbon
2. plants produce oxogen so it would lower the oxogen levels.
3. bacteria decomposes
2. Oxygen levels would fall drasically
3.bacteria plays a role in which it gets rid of harmful things in water
4. Vegetation Grows and cycles, water flows.
1. Pollution, burning of wood, grilling out, and driving cars.
2. If we remove too much vegetation the oxygen level would lower and there wouldn’t be enough Oxygen but we would have too much carbon dioxide.
3. Bacteria plays a huge role in all three cycles because it helps the plants grow and get nutrients.
1. They cars that run on gas and pollinate the air.
2. It would lessen the amount of oxygen in the atmosphere because it consumes carbon dioxide and produces oxygen.
3. Most of them are decomposers so it releases elements from dead material.
4. Nutrients are cycled through food chains, while energy is a one-way flow from the sun. You can recapture nutrients, but not energy.
5. The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
1. Humans exhale carbon dioxide.
2. The photosynthesis not being circulated will unbalance the oxygen levels.
5. Phosphorus erodes into the ground and is then absorbed by plants and animals. The Phosphorus cycle startes in rocks. When it rains, the phosphates and other minerals are removed from the rocks and distributed in soils and the water.
