N2 does not participate in the O2/C cycle. It is basically an inert gas that makes up most of the air you breathe.

Kiddo, this is a question that is easily answered if you put some work into it. Google, read your science text, go to the library, all ways to find out the answer. Simply going online to ask, is the lazy way, and not conducive to a good education.

When others do your work for you, you learn to always rely on others. Rely on yourself, and your brain, and figure it out. You'll learn more, and you'll be better off in the long run.
