• 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,

nitrogen through the biosphere.
A.) Nitrogen fixation: Break apart N2 so it can join
to other atoms and be used.
B.) Decay: Passes on through eating / waste.
C.) Plants with the help of bacteria take up
nitrogen.
D.) Denitrification: Nitrogen is removed from air.
