Question

Quizplus · Accepted Answer

Carbon cycles between the biotic and abiotic worlds mainly through the processes of cellular respiration and photosynthesis. During photosynthesis, autotrophic organisms such as plants absorb carbon dioxide from the atmosphere and convert it into glucose, which is then used as a source of energy. During cellular respiration, carbon is released back into the atmosphere in the form of carbon dioxide through the breakdown of glucose by heterotrophic organisms such as animals. This continuous cycle helps to maintain the balance of carbon in the earth's atmosphere.
