Jan 15, 2021 · The nitrogen cycle refers to the cycle of nitrogen atoms through the living and non-living systems of Earth. The nitrogen cycle is vital for life on Earth. Through the cycle, atmospheric nitrogen is converted to a form which plants can incorporate into new proteins.

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmospheric, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.
Jun 9, 2016 · In general, the nitrogen cycle has five steps: Nitrogen fixation (N2 to NH3/ NH4+ or NO3-) Nitrification (NH3 to NO3-) Assimilation (Incorporation of NH3 and NO3- into biological tissues) Ammonification (organic nitrogen compounds to NH3) Denitrification(NO3- to N2)
