Most organisms RELEASE dinitrogen after inhaling dinitrogen....all organisms to a first approximation...

Explanation:

And this is reasonable given that #N-=N# is a stable, strongly bound molecule, that is resistant to reaction. Of course, there are some nitrogen fixing-bacteria that can fix atmospheric nitrogen; these live in peas, beans, legumes etc. and participate in the nitrogen cycle.
