Question

Describe nitrogen cycle in details​

Answer 1

$\mathfrak{\huge{\orange{\underline{\underline{Answer :}}}}}$

The nitrogen cycle is the recycling phase of the nitrogen which includes nitrogen fixation, ammonification, nitrification, and denitrification. Denitrification is the process through which the nitrates and nitrites are converted back to atmospheric nitrogen. This process is performed by the anaerobic bacteria.

Answer 2

Answer:

Explanation:

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.

Some examples of the nitrogen cycle include the following: A plant takes nitrogen from the soil by absorbing it through its roots. ... Nitrogen can also get into the ocean through precipitation (rain). Nitrogen in the water undergoes fixation, which is generally facilitated by a bacteria called cyanobacteria.

In general, the nitrogen cycle has five steps:

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)
