Other living things cannot use atmospheric nitrogen.
Explanation: Most organisms cannot use N2 gas directly. Certain bacteria (and archaea) fix atmospheric N2 into ammonia or nitrates that plants and other organisms can take up. Bacteria also convert organic nitrogen back to N2 (denitrification), completing the cycle.
