Photosynthesis is done by producer. This process requires energy from sunlight and carbondioxide from abiotic matter. Photosynthesis makes energy storage molecules and oxygen for an ecosystem.
Explanation:
Photosynthesis is a process in which food is produced in the presence of sunlight. Carbondioxode enters through small opening called stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight, it produces two substances i. e. oxygen and glucose. Oxygen is released in the atmosphere and glucose is stored in different parts of plant body.
Animals needs oxygen's to survive and plants need carbon dioxide to survive. The ozone layer reflects harmful UV rays from the sun to protect the things living on Earth.
