To make energy, plants use . Animals, on the other hand, make energy through cellular respiration. These two processes are opposites.
Photosynthesis is the process that a plant uses to convert Carbon Dioxide and Water into Sugar and Oxygen, through the use of sunlight energy. The balanced equation can be seen here:
Cellular respiration is a process in which animals convert sugar and oxygen into carbon dioxide, energy, and water. Cellular respiration is divided into the steps Glycolysis, Krebs Cycle, and the Electron Transport Chain, which produce 2 ATP, 2 ATP, and 32 ATP, respectively. The equation for cellular respiration can be seen here:
