What is a major ecological significance of abundant atmospheric nitrogen?
Answer and explanation
Correct answer: It is the basic gas linked with proteins and the nitrogen cycle
Nitrogen is the most abundant gas in the atmosphere, but its ecological importance is not simply its quantity. Atmospheric nitrogen becomes useful to plants after fixation by certain bacteria or natural processes. Plants use the resulting compounds to make amino acids and proteins, while decomposition returns nitrogen to the soil and atmosphere through the nitrogen cycle. Option A is correct; nitrogen is not the main combustion gas, the sole cause of rainfall, or a direct blocker of all heat.
