Detailed explanation-1: -Consumers or heterotrophs such as humans and animals consume the organic molecules. Thus the organic carbon is passed through food chains and webs. The by-product of photosynthesis is oxygen, which plants release into the atmosphere through the stomata.

Detailed explanation-2: -Animals are called consumers, because they use the oxygen that is produced by plants. Carbon dioxide is released back into the atmosphere during respiration of consumers, which breaks down glucose and other complex organic compounds and converts the carbon back to carbon dioxide for reuse by producers.

Detailed explanation-3: -Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Detailed explanation-4: -Cellular respiration and photosynthesis can be described as a cycle, as one uses carbon dioxide (and water) and makes oxygen (and glucose), and the other uses oxygen (and glucose) and makes carbon dioxide (and water).

Detailed explanation-5: -Photosynthesis, respiration, and decomposition are processes that are responsible for maintaining the carbon dioxide-oxygen cycle. The process of photosynthesis in plants releases oxygen into the atmosphere. Was this answer helpful?
