Carbon dioxide is produced as a waste product.   A: The oxygen produced during photosynthesis is used in cellular respiration. The carbon dioxide produced in cellular respiration is used in photosynthesis. carbon dioxide and oxygen move through the ecosystem in this path called the CARBON DIOXIDE-OXYGEN CYCLE. A: During photosynthesis, algaet green plants take in CO2 from the air.
