PLEASE HELP I accidentally deleted all my answers to a test due in 10 minutes!!! Explain the role of bacteria in the nitrogen cycle.

Bacteria plays an important role as it helps in fixing nitrogen in the soil and within the root nodules of some plants, converts nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. ... Denitrifying bacteria converts nitrates back to nitrogen gas.

Hence they play an important role in nitrogen cycle.

In the nitrogen fixation process, nitrogen fixing bacteria converts the N 2 in the atmosphere into N H 3 (ammonia). This bacteria binds hydrogen molecules with the gaseous nitrogen to form ammonia in the soil. During assimilation, or when plants take up nitrates from the soil, bacteria aid in the process with the plants in making ammonia.
