NEET BIOLOGY

Detailed explanation-1: -Additionally, almost all the oxygen in the atmosphere is due to the process of photosynthesis. If photosynthesis ceased, there would soon be little food or other organic matter on Earth, most organisms would disappear, and Earth’s atmosphere would eventually become nearly devoid of gaseous oxygen.

Detailed explanation-2: -They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels. Without this process, life on Earth as we know it would not be possible.

Detailed explanation-3: -It ensures that all living species have access to oxygen in the atmosphere. It keeps the ecosystem’s oxygen and carbon dioxide levels in check. Plants are the source of fossil fuels. Energy is locked in fuel as a result of photosynthesis in the sun.

Detailed explanation-4: -The Sun! The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas.

Detailed explanation-5: -Photosynthesis is considered the most important process in biosphere due to following reasons: It is the primary source of food on earth. It is also responsible for the release of oxygen into the atmosphere by green plants which is needed by mostly all life forms.
