How is the stable proportion of nitrogen in the atmosphere indirectly useful for life?
Answer and explanation
Correct answer: It supports the nutrient system through the nitrogen cycle
Most organisms cannot use atmospheric nitrogen gas directly, but nitrogen-fixing organisms convert it into usable compounds. Through nitrates, ammonium and related substances, nitrogen enters soil, plants and food chains, supporting proteins and nucleic acids. Option A correctly describes this indirect life-supporting role. Nitrogen is not a direct energy source, does not form sunlight and cannot stop sea waves, so B, C and D are wrong.
