Question

Photosynthesis is the basis of life on earth. Explain.​

Answer 1

Answer:

Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. ... Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy.

Answer 2

Answer:

Photosynthesis provides the ultimate energetic basis for the activities of all human and animal life on Earth, because photo- synthetically produced organic mole- cules, when oxidized in respiration, can release the energy of the photons trapped during the original reduction of carbon dioxide.
