Answer:
· Nitrogen fixation
· Nitrification
· Assimilation
· Ammonification
· Denitrification
Step-by-step explanation:
Nitrogen fixation is the process where nitrogen is converting into ammonium.
Nitrification is the process of ammonium oxidation into nitrate.
Assimilation is the process where animals and plants receive NO3. Plants are using this nitrate for proteins and acids.
Ammonification is the process where the nitrate that is contained in plants and animals is recycled after their death.
Denitrification is e the last process in this cycle and during this process nitrate is converting to gases.
