A fellow student is studying the differences between photosynthesis and cellular respiration. The student asks you to explain how cellular respiration uniquely contributes to the carbon cycle. In 3–5 sentences, describe the different ways that both photosynthesis and cellular respiration contribute to the carbon cycle.

Both photosynthesis and cellular respiration are key processes that contribute to the carbon cycle. Photosynthesis, which occurs in plants and some other organisms, uses carbon dioxide from the atmosphere to produce glucose and oxygen. This glucose is then used in cellular respiration, a process that occurs in all living organisms, to generate energy, water, and carbon dioxide. Cellular respiration releases carbon dioxide back into the atmosphere, completing the carbon cycle by providing the necessary carbon dioxide for photosynthesis to occur again. Therefore, while photosynthesis removes carbon dioxide, cellular respiration contributes to its release, ensuring a continuous flow of carbon in the ecosystem.

Photosynthesis and cellular respiration are both vital processes in the carbon cycle. During photosynthesis, plants take in carbon dioxide from the atmosphere and convert it into glucose, thereby storing carbon in the form of organic compounds. On the other hand, cellular respiration is the process by which organisms release energy from glucose by breaking it down with oxygen. During this process, carbon dioxide is produced and released back into the atmosphere, completing the carbon cycle. Thus, photosynthesis helps remove carbon dioxide from the atmosphere, while cellular respiration contributes to the release of carbon dioxide back into the atmosphere.
