Describe in brief the role of nitrogen-fixing bacteria and lightning in atmospheric nitrogen fixation.

Asked by Topperlearning User 26th October 2016, 1:42 PM
Answered by Expert

Nitrogen-fixing bacteria (free-living or symbiotic) mostly found in the roots of leguminous plants convert atmospheric nitrogen to ammonia.

During lightning, the high temperature and pressure created in the air convert nitrogen to oxides of nitrogen.

These oxides dissolve in water to give nitrous and nitric acids which fall to the land along with rain.
