what process in which sunlight soil bacteria convert nitrogen compounds in soil back into nitrogen gas which is released into th
inn [45]

Denitrification is the major process involved in converting nitrogen components present in the nitrogen gas and it is released into the atmosphere.

<u>EXPLANATION: </u>

With the help of the nitrogen cycle, the nitrogen that enters living things by nitrogen fixation is converted back into nitrogen and is released in the atmosphere by microbes.

The nitrogen-fixing bacteria converts the nitrogen contents into ammonia by the process called ammonification. Then it oxidizes ammonia to nitrite by the process called nitrification and these nitrates are absorbed by plants.

Then, the bacteria present in the soil convert nitrate back to nitrogen gas which is released back to the atmosphere.
