Question

explain nitrogen cycle in 100 words

Answer 1

Nitrogen cycle is the biogeochemical process by which nitrogen is converted into different chemical forms as it circulates in the atmosphere and in the terrestrial and marine ecosystems. The various processes in the nitrogen cycle can broadly be classified as fixation, ammonification, nitrification and denitrification

Answer 2

Nitrogen is both the most abundant element in the atmosphere and, as a building block of proteins and nucleic acids such as DNA, a crucially important component of all biological life. The nitrogen cycle is a complex biogeochemical cycle in which nitrogen is converted from its inert atmospheric molecular form (N2) into a form that is useful in biological processes
