This is a biogeochemical cycle in which nitrogen is converted from its inert atmospheric molecular form (n2) into a form that is useful in biological processes. the cycle includes fixation, nitrification, assimilation, ammonification, and finally denitrification, when nitrogen is returned to the atmosphere.

Nitrogen cycle

Explanation:

Nitrogen cycle is a example of a biogeochemical cycle in which nitrogen is converted into multiple chemical forms as it circulates between the biosphere and the atmosphere.Nitrogen happens to be an important nutrient for the survival of all living organisms. Despite the fact that nitrogen is abundant in the atmosphere many living organisms can not access it in this form, and it has to be converted to forms that can be used by living organisms. This is done through various processes in the nitrogen cycle.

Ithink its false. hope this : )
