None of the above

Detailed explanation-1: -It is the source of energy and food for all organisms. It releases oxygen into the environment which is utilised by organisms.
Detailed explanation-2: -This process takes in oxygen from the atmosphere and releases carbon dioxide. Photosynthesis – plants produce their own food in the form of glucose using the process of photosynthesis. This process uses sunlight (and so only occurs during the day) to remove carbon dioxide from the atmosphere and release oxygen.
Detailed explanation-3: -The balance of oxygen and carbon dioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbon dioxide released by humans, animals, and plants etc. during respiration.
Detailed explanation-4: -Photosynthesis is the process in which autotrophs such as green plants use carbon dioxide and water in presence of sunlight to synthesize nutrients such carbohydrates in the form of glucose and release oxygen. Hence oxygen is returned to the atmosphere by photosynthesis.
Detailed explanation-5: -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.
