Arrange these steps in the nitrogen cycle in the correct order to explain how nitrogen from the atmosphere cycles through the other spheres o Earth.

The correct order is:

1) dead organic matter

2) ammonification

3) nitrification – yielding nitrite

4) nitrification yielding nitrate

5) denitrification  

6) biosphere

7) Fixation

Explanation:

Decomposers take nitrogen from the tissues and change into ammonia or salts of ammonia, NH₃, and NH₄ (Ammonification).   At that point, by nitrification, these structures are prepared and changed first into nitrite NO₂ and afterward into nitrate NO₃.   Autotroph creatures take nitrogen from the dirt as nitrate, NO₃. Plants reduced this oxidated nitrogen, NO₃, to the amino group by the assimilation process.  

Along these lines, organisms take nitrogen from plants as an amino group, NH₂.  Other microbes use nitrate NO₃ and by denitrification produce atmospheric N₂ and back it to the environment.   From the climate, some other microorganisms focus N₂ in the plants' underlying foundations or in the dirt.
