Why is nitrogen called indirectly important for life among atmospheric gases?
Answer and explanation
Correct answer: Because it is linked with proteins of organisms and the nitrogen cycle
Atmospheric nitrogen is abundant but most plants and animals cannot use nitrogen gas directly. Nitrogen-fixing bacteria and lightning convert it into compounds that plants can absorb; plants then use nitrogen to make proteins and other essential molecules, and animals obtain it through food. This connection with the nitrogen cycle explains its indirect importance. Hence option A is correct, while B, C and D are false.
