Why is photosynthesis is important to people and organisms?

Answer 1

Best Answer - Chosen by Voters

Animals and plants both synthesize fats and proteins from carbohydrates; thus glucose is a basic energy source for all living organisms.

The oxygen released (with water vapor, in transpiration) as a photosynthetic byproduct, principally of phytoplankton, provides most of the atmospheric oxygen vital to respiration in plants and animals, and animals in turn produce carbon dioxide necessary to plants.

Photosynthesis can therefore be considered the ultimate source of life for nearly all plants and animals by providing the source of energy that drives all their metabolic processes.

Answer 2

without photosyntheis plants cant get energy. with out plants having energy eventually it will affect every living thing


--> This is because photosynthesis helps produce oxygen for humans to breathe.

photosynthesis is important because it help plants grow and a tree is a plant and with out it humans and land animals would die of no oxygen. this would soon effect things like fish sharks and other things that live in the water. everything on earth would die and the living things would seis to exist

Answer 3

Photosynthesis produces oxygen gas, which is essential for human respiration. Respiration also depends on food as a source of chemical energy. Plants use photosynthesis to make carbohydrates from water and carbon dioxide. These carbohydrates are food for many animals, which themselves become food for larger animals. All this food is then available to humans, but it would not exist without photosynthesis.

Answer 4

Photosynthesis is important to all living things because when plants make food during it, herbivores (plant eaters) eat the plants, gaining the energy. When carnivores (meat eaters) eat the herbivores, they gain the energy.

Answer 5

Because without photosynthesis there would be no plants such as trees, grass, grains, weeds, or the myriad of food plants for humans and animals.

Answer 6

it is important for all living organisms because plants rely on photosynthesis to survive and grow. If all plants die out, all other living organisms will have disastrous affects.
