In bioaphere how do plants and animals are complementary systems, which are integrated to sustain life?

Explanation

In plants, oxygen enters through the stomate and it is transported to cells, where oxygen is utilized for energy production. Plants require carbon dioxide to survive, to produce carbohydrates and to release oxygen through photosynthesis. These oxygen molecules are inhaled by human through the nose, which reaches the lungs where oxygen is transported through the blood and it reaches cells. Cellular respiriation takes place inside or the cell for obataining energy.
