Photosynthesis can be considered the fundamental life process for nearly all plants and animals. It provides the source of energy that drives all their metabolic functions and the oxygen required for respiration.
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.
The main reason why photosynthesis is essential for living and animals because photosynthesis allows plants to make glucose, which is need to make energy and cellular structures. Photosynthesis is also the main source of food on earth. It release oxygen which is an important element for survivals
