Cycles of Matter
- Carbon
Cycle
- Animals and plants break
down sugars and release
carbon dioxide
- When an organism dies
carbon stored inside of them
goes to the soil.
- Nitrogen
Cycle
- In the nitrogen cycle, nitrogen moves
from the air into the soil, into living
things, and back into the air or soil.
- The air around us is about
78% nitrogen gas.
- Nitrogen is called
''free'' nitrogen because
it is not combined
with other kinds of
atoms
- Oxygen
Cycle
- Producers release oxygen
as a result of
photosynthesis.
- Most organisms take in oxygen
from the air or water and use it to
carry out their life processes.
