Answer

  1. Respiration: Organisms, including plants and animals, release carbon dioxide back into the atmosphere during respiration as they break down sugars for energy.

  2. Decomposition: When organisms die, decomposers such as bacteria and fungi break down their bodies, releasing carbon dioxide as a byproduct of this process.

  3. Combustion: When organic material such as wood or fossil fuels is burned, it releases carbon dioxide into the atmosphere, contributing to the cycling of carbon.
