Through which process is the biological relation between carbon dioxide and oxygen in the atmosphere most clear?
Answer and explanation
Correct answer: Photosynthesis and respiration
The governing concept is the biological exchange of gases in the carbon–oxygen cycle. During photosynthesis, green plants use carbon dioxide and water to make food and release oxygen. During respiration, organisms use oxygen to release energy from food and produce carbon dioxide. Thus option A identifies the linked processes. Earthquakes, tides and magnetism are physical phenomena and do not explain this regular biological exchange.
