what biogeochemical cycle are the processes of photosynthesis and cellular respiration a part of
The Carbon Cycle. There is a relationship between photosynthesis and cellular respiration. Cellular respiration releases carbon dioxide, which is used in photosynthesis.Photosynthesis in turn releases oxygen used in respiration. Animals and other heterotrophs depend on green organisms for organic food, energy, and oxygen. In the carbon cycle, organisms exchange carbon dioxide with the atmosphere.ellular respiration releases carbon dioxide, which is used in photosynthesis. Photosynthesis in turn releases oxygen used in respiration. Animals and other heterotrophs depend on green organisms for organic food, energy, and oxygen.
