How does the nitrogen that is a part of the living
system returns back to the atmosphere?
Lightning converts compounds of nitrogen into
gaseous nitrogen
Bacteria convert compounds of nitrogen into
gaseous nitrogen
Uptake of nitrogenous compounds by plants
Bacteria fix nitrogen into nitrogenous
compounds​

Answer 1

Answer:

Through lightning: Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall. Industrially: People have learned how to convert nitrogen gas to ammonia (NH3-) and nitrogen-rich fertilisers to supplement the amount of nitrogen fixed naturally
