         <description><![CDATA[Nitrogen is a crucial element for our survival because it is an integral part of many cellular components such as nucleic acids, proteins, vitamins, etc. Nitrogen is also an important constituent of chlorophyll in plants. Plants cannot obtain their nitrogen directly from the air, instead, they rely on bacteria and archaea present in the soil to break down the nitrogen into a usable form. Hence, a complex, interconnected network systems helps in maintaining the concentration of nitrogen in the atmosphere and also to ensure the survival of dependent lifeforms.

Basically, nitrogen cycle is the re-circulation and re-use of nitrogen in various forms to meet the demand for various environmental and biological activities. Nitrogen in the atmosphere is present in a diatomic form i.e., N2. Therefore, plants cannot use the nitrogen in this form. Therefore, they need nitrogen fixing bacteria, lightning, root nodules, forest fire etc to convert the nitrogen into nitrate compounds like NO, NO2, NO3.]]></description>
