- Nitrogen is the major part of the air we breathe, but it is unreactive, therefore, not participate in respiration at all so, nitrogen breathe out again.
- Nitrogen fixation: conversion of atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation, mainly fixed by bacteria.
