What happens to the carbon cycle when primary and secondary producers die?

When primary and secondary producers die, the carbon they contain is released back into the environment through decomposition. Decomposers, such as bacteria and fungi, break down the organic matter, releasing carbon dioxide into the atmosphere and nutrients into the soil. This process not only recycles carbon but also supports the growth of new plants, maintaining the balance of the carbon cycle. Additionally, some carbon may be stored in sediments, contributing to long-term carbon sequestration.
