Question

Why is photosynthesis important to all life on earth?

Answer 1

Hint: Photosynthesis is the process of making food by plants in which plants use sunlight, water, and carbon dioxide. In other words plants convert sunlight, water and carbon dioxide to chemical energy in the form of sucrose.

Complete answer:
Photosynthesis is important to all life on earth as it is the number one source for releasing oxygen directly into the atmosphere.
It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet. without photosynthesis, the carbon cycle could not occur, oxygenated organisms don't survive and plants eventually die. Green plants and microbes use sunlight to make their food. If photosynthesis does not occur, all organisms dependent on it would die. It produces oxygen which we inhale . Without photosynthesis the existence of life on the earth is impossible.
It contributes to the symbiotic association between plants, microbes and animals.
Light is absorbed by tiny organelles in the leaves and it is processed via a chemical reaction and then stored in the plant. When herbivores feed upon it, it gets transferred to the consumer.

Note:
Photosynthesis transforms sunlight, carbon dioxide and water into chemical energy that plants use. It also releases oxygen as a by-product into the atmosphere. Animals use the chemical energy that the plants make during photosynthesis to get their energy.
