Answer :
- Plants can't utilize nitrogen from the atmosphere unless it's fixed. Microorganism like Bacteria, either free-living or symbiotic, do the majority of nitrogen fixation.... They have a nitrogenase enzyme that produces ammonia by combining gaseous air nitrogen with hydrogen.
- Nitrogen-fixing bacteria are microorganisms that can convert nitrogen from the atmosphere into fixed nitrogen. These species are responsible for more than 90% of all nitrogen fixation, and hence play a vital part in the nitrogen cycle.
