The nitrogen cycle is a biogeochemical process in which nitrogen is transported from the atmosphere to living organisms and then returned to the atmosphere in various forms.
The creation of nucleic acid and proteins in living organisms requires nitrogen. Nearly 78 percent of nitrogen in the atmosphere is in an inert state (N2). Living organisms cannot use this nitrogen until it is transformed to ammonia, nitrates, and other nitrogen-based molecules.
Nitrogen compounds nourish the soil, making it fertile and ideal for plant growth.
Nitrogen is an important component of living creatures cells and tissues. Proteins and nucleic acid are the building blocks of life. Life could not survive without nitrogen molecules.
The nitrogen released by the combustion of fuels and fertilisers contributes to the growth in nitrogen levels in the atmosphere.
Chlorophyll is a pigment that is required for photosynthesis. The nitrogen cycle aids plants in producing chlorophyll from nitrogen compounds.
Plants require nitrates to survive and thrive, hence it is vital for their existence.
