Question

rganisms participate in the nitrogen cycle. It is an important component of
proteins and nucleic acids. As compared to other elements, it is inactive and does not
easily combine with other elements. Most organisms cannot use the free form of nitrogen.
Important processes of the nitrogen cycle
1. Nitrogen fixation: Conversion of nitrogen into nitrates and nitrites through atmospheric,
industrial and biological processes.
2. Ammonification: Release of ammonia through decomposition of dead bodies and
excretory wastes of organisms.
3. Nitrification: Conversion of ammonia into a nitrite and then nitrate.
4. Denitrification: Conversion of nitrogen compounds into gaseous nitrogen.
