Question

Nitrogen is the most common element in the air. Why do bacteria play a role in the nitrogen cycle

Answer 1

Bacteria play a role in the nitrogen cycle because:

The bacteria’s helps in breaking down the organic materials which has nitrogen in it, and helps in giving the nitrogen back to the cycle. Bacteria helps in breaking down of the leaves and then it diffuses the nitrogen to the soil. Prokaryotes also plays an important role in the nitrogen cycle. The nitrogen fixing bacteria present in the root zone of plants basically in the soil, helps in conversion of the nitrogen into ammonia. Then the nitrifying bacteria converts the ammonia to the nitrites or can say nitrates.
