• All life requires nitrogen-compounds, e.g., proteins and nucleic acids.

• Air, which is 79% nitrogen gas (N2), 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 (NO3−) – ammonia (NH3) – urea (NH2)2CO

• Animals secure their nitrogen (and all other) compounds from plants (or animals that have fed on plants).

• Nitrogen in atmosphere is inert (N2 Gas) which is not reactive. (Can’t use)– Bacteria on plant roots convert nitrogen in

atmosphere into • nitrate ions (NO3−) (NO2-)• ammonia (NH4)

• Four processes participate in the cycling of nitrogen through the biosphere.– Nitrogen fixation: Break apart N2 so it can join to

other atoms and be used.
