Why is photosynthesis so important to living organisms?
konstantin123 [22]

Answer:

All living organisms need energy to stay alive, but only producers can directly convert energy into food.

Explanation:

The process of photosynthesis is very important because all living organisms need energy to stay alive, but only producers can directly convert energy into food.

Photosynthesis is the process whereby green plants manufacture their food in the presence of carbon dioxide and water.

  • They take light energy from the sun and produce food materials.
  • The light energy is converted to chemical energy which are stored in carbon chains as glucose.
  • The  chemical energy is then used by other living organisms for their own nourishment.
