Question

List the steps involved in nitrogen cycle

Answer 1

Answer:

Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)

Nitrification (NH3 to NO3-)

Assimilation (Incorporation of NH3 and NO3- into biological tissues)

Ammonification (organic nitrogen compounds to NH3)

Denitrification(NO3- to N2)

Answer 2

there are 5 steps in the nitrogen cycle  

1)Nitrogen fixation

2)Assimilation

3)Ammonification

4)Nitrification

5)Denitrification

---------------------------------------------------------------------------

1)Nitrogen fixation

in this step nitrogen is fixed r by microorganisms to the soil and the fixation of nitrogen is done by symbiotic bacteria and some other microorganisms

2)Assimilation

in this  process the plants take up the nitrogen present in the soil for their own purpose and other organisms get nitrogen by consuming plants , ammino acids etc

3)Ammonification

When a plant or animal dies , the nitrogen will be in organic form and the microorganisms like bacteria or fungi convert the organic nitrogen into ammonia  

4)Nitrification

In this step ammonium is converted into Nitrate by nitrifying bacteria and there are many reactions taking place dureing the conversion

5)Denitrification

In this process nitrate is converted into nitrogen gas which completes the nitrogen cycle
