Why is the dominance of nitrogen among permanent atmospheric gases most suitably important for Earth's biosphere?
Answer and explanation
Correct answer: It keeps combustion controlled and is linked with the nitrogen cycle
Nitrogen is the most abundant permanent atmospheric gas and is relatively unreactive under ordinary conditions. Its abundance helps dilute oxygen, so combustion does not proceed uncontrollably, while the nitrogen cycle converts nitrogen into forms that organisms can use to build proteins and nucleic acids. Option A captures both ideas. Nitrogen does not heat plants directly, form the ozone layer, or acidify every raindrop.
