Carbon and Phosphorus Cycle

Carbon and Phosphorus Cycle

• By Steve Kim, Francisco Park, David Kim

2
Carbon Cycle

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

3

• People burn fossil fuels and carbon is released
  into the atmosphere.
• Carbon dioxide traps heat inside the Earths
  atmosphere.

4

• 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.

5
Key Words

• biosphere ?? ecosystem

6
Phosphorus Cycle

• 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.)

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.

9

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

Key Words

• DNA
• RNA
• biological compounds
