Step 4
A
Ammonification
5
Q
Nitrogen Fixation
A
Bacteria changes Nitrogen into Ammonium
6
Q
Nitrification
A
Ammonium gets changed into nitrates by soil bacteria. Plants can now absorb nitrogen in the form of nitrate. (NH4+1 to NO2-1 to NO3-1)
7
Q
Assimilation
A
Plants absorb the nitrates from the soil.
8
Q
Denitrification
A
Converts nitrates to nitrogen gas released into the atmosphere. NO3-1 to N2
9
Q
Ammonification
A
Decomposers (bacteria) turn the nitrogen from dead animals / plants back into ammonium
