73. All life requires nitrogen-compounds, e.g., proteins and nucleic acids. Air, which is 79% nitrogen gas (N 2 ), is the major reservoir of nitrogen. But most organisms cannot use nitrogen in this form. Plants must secure their nitrogen in "fixed" form, i.e., incorporated in compounds such as: nitrate ions (NO 3 −) ammonia (NH 3 ) urea (NH 2 )2CO Animals secure their nitrogen (and all other) compounds from plants (or animals that have fed on plants).
