When bacteria and fungi decompose animals and plants ammonium is also produced.

If plants are eaten by animals, when they die they are also decomposed by bacteria and fungi.

# data[].attributes.body
Plants then could either be eaten by animals, or die and be decomposed by bacteria and fungi

Another possibility is that Assimilation can happen where Nitrate is absorbed by plants.

After bacteria makes nitrates, it can either be denitrified by bacteria and nitrogen is produced back into the atmosphere.

# data[].attributes.body
Then more of that bacteria turn the nitrites into nitrates (NO3-).

Then another type of bacteria turns the ammonium in the ground into nitrites (NO2-). This process is called nitrification.

# data[].attributes.body
It is then absorbed into the ground and bacteria turn it into Ammonium (NH4+).
This process it called Ammonification.

# data[].attributes.body
The process starts with Nitrogen in the atmosphere. This nitrogen mostly comes from when the earths atmosphere was mainly methane and ammonia.
