2. They are able to use photosynthesis in the same way as plants.
3. They absorb their nutrition from other organisms, living or dead.
4. They don't need a food supply; they live only a short while.

Why are fungi so important to the carbon cycle?
1. They produce O2, making it available to nearby plants for use in the carbon cycle.
2. They release water from the soil, freeing up hydrogen atoms for the carbon cycle.
3. They make it turn more rapidly by breaking down wood, freeing up carbon atoms.
4. They fix carbon and produce O2 just like plants do during photosynthesis.
