Summary Introduction

Introduction:

Nitrogen cycle represents a bio-geo chemical cycle in which nitrogen and its compounds change from one form to another through interaction with different trophic levels. The atmospheric nitrogen is captured by nitrogen fixing bacteria, which produce ammonia. Other bacteria convert ammonia to nitrate. Nitrogen passes from one trophic level to another and finally returned to the atmosphere by denitrifying bacteria.
