Answer:
B)Photosynthesis releases oxygen into the atmosphere while aerobic respiration removes oxygen from the atmosphere.
Explanation:
Only option B satisfies the answer to the question.
We know that photosynthesis is the process whereby green plants manufacture their foods in the presence of carbon dioxide and sunlight. Carbondioxie in the environment is used to manufacture food in plants. The bye product of photosynthesis is oxygen gas. Oxygen gas is used for aerobic respiration in animals and is essential for their life. This way photosynthesis adds to the pool of oxygen in the atmosphere and aerobic respiration removes from the pool.
