Final answer:
Cellular respiration and photosynthesis are interdependent processes that exchange gases and energy. Photosynthesis uses carbon dioxide and water to produce glucose and oxygen, while cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and ATP.
Step-by-step explanation:
Cellular respiration and photosynthesis are interdependent processes. While photosynthesis uses carbon dioxide and water to produce glucose and oxygen, cellular respiration uses glucose and oxygen to produce carbon dioxide, water, and ATP. This exchange of gases and energy between photosynthesis and cellular respiration helps maintain stable levels of oxygen and carbon dioxide in the atmosphere.
