Final answer:
Oxygen is a reactant of photosynthesis while being the product for aerobic respiration.
Step-by-step explanation:
Oxygen is a reactant of photosynthesis while being the product for aerobic respiration.
Photosynthesis is the process by which plants and other organisms convert carbon dioxide and water into glucose and oxygen, using sunlight as the energy source. Oxygen is released as a byproduct of photosynthesis and is then used by organisms for aerobic respiration.
Aerobic respiration is the process by which living organisms convert glucose and oxygen into carbon dioxide, water, and energy (ATP). Oxygen is consumed during this process and carbon dioxide is produced as a waste product.
