Why is it incomplete to limit the role of oxygen among atmospheric gases only to respiration?
Answer and explanation
Correct answer: Because oxygen also participates in combustion and oxidation processes
Oxygen supports aerobic respiration, but its atmospheric importance is broader. It enables combustion and participates in oxidation, including the rusting of metals and decomposition of many substances. These processes release or transfer chemical energy and alter materials in ecosystems and human activities. Option A is correct. Options B and C confuse oxygen with unrelated substances, while D is false because oxygen is a major atmospheric gas.
