Question

whãt îs nitrogen cycle​

Answer 1

Answer:

the series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

Answer 2

Explanation:

Nitrogen is important for living organisms to produce a number of complex organic compounds like amino acids, building blocks of proteins and nucleic acids (DNA and RNA). Though nitrogen is abundantly available in atmosphere as dinitrogen (N2), it can not be directly used by living organisms. It needs to be fixed before being utilised by the primary producers, i.e. plants. In the same way, before being released in the atmosphere in the end, it should again be converted in the form it originally was. This complete transfer of nitrogen from the atmosphere to living beings and then back to the atmosphere represents the nitrogen cycle.
