Summary Introduction
To enlist:
Four reactions which are involved in the nitrogen cycle.
Concept introduction:
In nature, nitrogen is present in abundance. It constitutes around 79% of air, but nitrogen is not available in a free form to the organisms. Nitrogen cycle refers to the circulation of nitrogen between the atmosphere and the organisms.
