Question

list down the step of nitrogen cycle and mention the role of micro organism in each step ( Class 9 )​

Answer 1

Answer:

In general, the nitrogen cycle has five steps:

Nitrification (NH3 to NO3-) Assimilation (Incorporation of NH3 and NO3- into biological tissues) Ammonification (organic nitrogen compounds to NH3) Denitrification(NO3- to N2)

Explanation:

Prokaryotes play several roles in the nitrogen cycle. Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. ... Denitrifying bacteria converts nitrates back to nitrogen gas.
