Why are photosynthesis and respiration important to plants and animals?
Photosynthesis is a process for plants to make their food in layman's term. However, photosynthesis is more complicated but the general is that it's a process for plants to convert light energy to chemical energy which is their fuel. Respiration is inhaling oxygen and exhaling carbon dioxide to simply put it. So when animals exhale, they exhale carbon dioxide which their lungs converted to from oxygen.Carbon dioxide is a factor for photosynthesis. Photosynthesis is like respiration. Animals inhale oxygen and exhale carbon dioxide. Plants, one would say they inhale carbon dioxide and exhale oxygen. So animals give plants carbon dioxide while plants give animals oxygen.
