Which statement about atmospheric nitrogen is the most balanced?
Answer and explanation
Correct answer: It is most abundant but not directly usable by all organisms
The governing concept combines atmospheric composition with the nitrogen cycle. Nitrogen forms about 78% of dry air, making it the most abundant major gas, but most organisms cannot use atmospheric N₂ directly. Nitrogen fixation and related biological or industrial processes convert it into usable compounds. Therefore option A is correct; the other statements wrongly describe its abundance, origin, or greenhouse role.
