1. Carbon and Phosphorus Cycle By Steve Kim, Francisco Park, David Kim

2. Carbon Cycle Plants use Carbon dioxide and sunlight for energy. Plants use Carbon dioxide and sunlight for energy. Plants die and turn into fossil fuels like oil and coal. Plants die and turn into fossil fuels like oil and coal.

3. People burn fossil fuels and carbon is released into the atmosphere. People burn fossil fuels and carbon is released into the atmosphere. Carbon dioxide traps heat inside the Earth’s atmosphere. Carbon dioxide traps heat inside the Earth’s atmosphere.

4. Some animals absorb carbon to build their tissues. Some animals absorb carbon to build their tissues. When the animals breath carbon dioxide is released, also when they die the carbon is absorbed into the soil. When the animals breath carbon dioxide is released, also when they die the carbon is absorbed into the soil.

6. Phosphorus Cycle Phosphorus Cycle is the movement of phosphorus from land to sediments in the seas and then back to land. Phosphorus Cycle is the movement of phosphorus from land to sediments in the seas and then back to land.

7. On Earth, phosphorus is usually found in water, soil and sediments. (Phosphorus usually liquid when normal temperature.) On Earth, phosphorus is usually found in water, soil and sediments. (Phosphorus usually liquid when normal temperature.)

8. Phosphorus moves from and deposits on land and also in sediments. This then is moved to living organisms. Then it is transferred back to land. Phosphorus moves from and deposits on land and also in sediments. This then is moved to living organisms. Then it is transferred back to land.

9. Phosphorus aids in plant growth. That is why we often use phosphorus fertilizer. Phosphorus aids in plant growth. That is why we often use phosphorus fertilizer.
