Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle.
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. While cellular respiration releases carbon dioxide into the environment and produces ATP thanks to oxygen and glucose, photosynthesis pulls carbon dioxide out of the atmosphere and produces oxygen and nutrients from water and CO2
