Which pair of processes shows the opposite biological exchange of oxygen and CO₂ in atmospheric composition?
Answer and explanation
Correct answer: Photosynthesis and respiration
During photosynthesis, green plants use carbon dioxide and water to form food and release oxygen, usually with light energy. During respiration, organisms use oxygen to release energy from food and produce carbon dioxide and water. These processes therefore move the two gases in opposite directions. Option A is correct; the other pairs are not biological gas-exchange processes.
