Summary Introduction
To review:
The mechanism of the global nitrogen cycle and the organisms that drive it.
Introduction:
Nitrogen is an important inorganic element present in the body of living organisms and is a constituent of basic proteins, DNA (deoxyribonucleic acid), and enzymes. High amount of nitrogen concentration is present in the earth’s atmosphere and nitrogen cycles operate to recycle the nitrogen from an atmospheric pool, to smaller pools and living organisms.
