The nitrogen cycle is a
biogeochemical succession process of nitrogen that involves: fixation,
ammonification, nitrification, and denitrification. Like any other
biogeochemical cycles. This process undergoes and affects the biological, geometrical
and chemical aspects in the ecosystem and the abiotic and biotic community. Hence,
the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the
biotic community, decomposition and primal production. Further, it becomes an
essential part of the environment because some life components are contains it,
similarly, amino acids, nucleic acids in RNA and DNA. </span>
