Answer:
Four abiotic forms of nitrogen cycle and its chemical formula
Ammonium – [tex]NH^{4+}[/tex]
Ammonia – [tex]NH^3[/tex]
Nitrite – [tex]NO^2[/tex]
Nitrate – [tex]NO^3[/tex]
Explanation:
Ammonium: In the nitrogen cycle ammonium is starting point that is present in soil and are converted to various forms by different process.
Ammonia: In the process of nitrogen fixation, the bacteria having nitrogenase enzymes reacts with the nitrogen as well as hydrogen and produces the ammonia, which is further converted to organic compounds.
Nitrite: The nitrosomonas bacteria present helps in conversion of nitrogen gas into nitrite.
Nitrate: Again the Nitrite is converted into Nitrate by the nitrobacter. During the process of assimilation ammonium and nitrate are absorbed by the plants.
