Combustion, feeding, photosynthesis, respiration

Accepted Answer

The carbon cycle involves the interconversion of carbon compounds as they circulate in the environment. For e.g., carbon dioxide is released into the atmosphere through respiration by animals, burning of fossil fuels, and several other ways. Plants take up CO₂and convert it into sugars via photosynthesis.

Decomposition of the dead organic matter by decomposers such as bacteria and fungi cycles the carbon back into the atmosphere. These soil microbes secrete digestive enzymes that break down the complex organic substances, releasing carbon dioxide.
