How does nitrogen return to the atmosphere? Phosphorus Cycle 1. Why is phosphorus important to living organisms? 2. How is the phosphorus cycle different from the nitrogen or carbon cycles

Answer 1

Water Cycle:


1. It is stored in the ground.

2. Evaporation, transportation, precipitation

3. Runoff comes straight from precipitation. Infiltration is from the ground while run off never went in the ground.

4. It will usually end up in the same place, the ocean

5. Water levels rise, temperatures rise, CO2 in atmosphere increases


Carbon Cycle:

1. Carbon is important because it is one of the basic building blocks of life.

2. Trees, animals, grass, decomposition, combustion, fossil fuels

3. Carbon enters as photosynthesis.

4. Carbon enters water to the soil decomposition. Aquatic plants have plenty of water to work with, so their main challenge is getting enough sunlight and air.

6. By breathing in the oxygen from plants.

7. Two ways carbon return from animals into water is through cellular respiration and decomposition.

8. Combustion is when we dig up the fossil fuel and burn it, then what is left goes into the air starting the cycle again.

9. Deforestation reduces the capacity of forests to be carbon sinks.


Nitrogen Cycle:

1. Nitrogen is important because it helps us grow crops, and it produces grass for animal.

2. It comes from lightning and is named nitrogen fixation.

3. Ammonification and then transitions into nitrification and then to assimilation.


Phosphorus Cycle:

1. It forms part of life sustaining molecules like DNA and RNA.

2. Phosphorus is never found in the atmosphere.
