How are photosynthesis and aerobic respiration interlinked with each other?

Photosynthesis and aerobic respiration are interlinked because the products of one process are the reactants of the other. In photosynthesis, plants produce oxygen and glucose using sunlight, water, and carbon dioxide. In aerobic respiration, organisms (including plants) use oxygen and glucose to produce carbon dioxide, water, and ATP. This creates a cycle where the oxygen and glucose produced by photosynthesis are used in respiration, and the carbon dioxide and water produced by respiration are used in photosynthesis.
