What role do producers and consumers play in the carbon cycle

Carbon cycle refers to the biogeochemical cycle by which carbon is exchanged between atmosphere, hydrosphere, geosphere, and biosphere.

Producers like plants use carbon dioxide present in the atmosphere and fix carbon into organic compounds.  

Thus, producers fix carbon and make it available in usable forms for consumers.

Consumers use carbon in the form of organic compounds such as glucose and use it for cellular respiration. It releases carbon back into the atmosphere in the form of carbon dioxide.

Thus, consumers return carbon to the atmosphere.
