The nitrogen , then turn into ammonia when it breaks down in the soil.
It is what helps nitrogen viable to plants.
Nitrogen fixation is the first step.

NITRIFICATION
Look my friend is going under the soil
It is when the bacteria in the soil turns ammonia into nitrates .That is what the plants absorbs. Bacteria plays an important role in this cycle because it helps nitrogen change in between each stages.
Nitrification happens next.

ASSIMILATION
This is when the plants really get the nitrogen because as plants absorb the nitrates, it gets used in amino acids and nucleic acids.
Look at the plants, they are absorbing the nitrogen
This process is called assimilation

AMMONIFICATION
Look over there it is a dead animal
Now here Ammonification can take place
Decomposers like fung or bacteria turn the nitrogen back into ammonia so it can be in the nitrogen cycle again.

when extra nitrogen in the soil gets back into the atmosphere.
