Nitrogen in its most common form N2 is very stable the triple bond between the two atoms takes a lot of energy to break. Compared to O2 which only has a double bond between them meaning it’s much more reactive.

Both nitrogen and oxygen are necessary for life, but they have different chemical properties that mean they’ll be used in different ways.
