In science class we learned about the Carbon Cycle, and organic and inorganic carbon and all stuff relating to that. There are many things I don't understand, but here's what I need to know:

What exactly is the Carbon Cycle?

Why is photosynthesis and cellular respiration complementary to each other (what is cellular respiration, anyway)?

Why are decomposers so important in the Carbon Cycle?

Hopefully I can have someone help me on some of these things if not all.
