Water cycle 1. how is water stored on earth during the water cycle? 2. water moves into the atmosphere through and and returns to the earth through 3. what is the difference between infiltration and runoff? 4. where do groundwater and runoff usually end up? 5. what are three ways global warming might affect the water cycle? carbon cycle 1. why is carbon important? 2. what are seven places that carbon exists? 3. how does carbon enter the biotic part of the ecosystem, namely plants from the atmosphere? 4. how does it enter the soil? 5. how does carbon enter water? how do aquatic plants get carbon? 6. how do animals get carbon? 7. what are two ways carbon returns from animals into the water? 8. what is combustion, and how does it affect the carbon cycle? 9. how does deforestation affect the carbon cycle? nitrogen cycle 1. why is nitrogen important? 2. how is nitrogen from the atmosphere, the abiotic part of the ecosystem, converted in to the biotic part of the ecosystem in organisms? 3. how do consumers get nitrogen? 4. 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

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.
