Cycles of Matter
- The Carbon Cycle
- Most producers take in carbon
dioxide from the air during
food-making or photosynthesis.
- Producers use it to make food.
- They use the carbon that
contain molecules such as
sugars and starches.
- When food is broken down,
the consumers and producers
release carbon dioxide and
water into the environment.
- The 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.
- Nitrogen Fixation
- It is when free nitrogen is
changed into usable nitrogen,
performed by some bacterias.
- Producers can use it
to build proteins and
other complex
compounds.
- Most of the
nitrogen fixation is
made of bacteria.
- These bacteria live in
bumbs and it is called
nodules, on the roots of
legumes.
