Question

List the 4 abiotic forms of nitrogen cycle and the chemical formula

Answer 1

Four abiotic forms of nitrogen cycle and its chemical formula

Ammonium –
`NH^(4+)`

Ammonia –
`NH^3`

Nitrite –
`NO^2`

Nitrate –
`NO^3`

Step-by-step 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.
