Quick Recall Flashcards

How does decomposition return carbon to the atmosphere?

Decomposers (bacteria and fungi) break down dead organisms. They respire, releasing CO₂ back into the atmosphere. Without decomposers, carbon would be locked in dead material forever.

What does the carbon cycle do?

The carbon cycle continuously moves carbon between the atmosphere (as CO₂), living organisms, the soil, and fossil fuels. Carbon is never created or destroyed — it is recycled.
