why is photosynthesis and cellular respiration considered to be complementary processes
Photosynthesis takes Carbon dioxide, Water and light energy and makes Sugars and Oxygen. Cellular respiration takes Sugars and Oxygen and makes Carbon dioxide, water and energ â¦ y. The two processes are the inverse of one another one stores energy and the other releases that stored energy.ecause the reactants required for cellular respiration (glucose and oxygen) are the products of photosyntheses And the and the products of cellular respiration (carbon dio â¦ xide and water) are the reactants of photosynthesis.
