Answer: Nitrogen fixation

Explanation:

Nitrogen cycle is one of the important biogeochemical cycle. It involves the movement of nitrogen and it's forms into atmosphere, pedosphere, and biosphere.

The atmospheric nitrogen cannot be directly absorbed by the plants for their growth. Thus they receive the important forms of nitrogen like nitrates, nitrites and ammonia from the bacteria associated symbiotically. The soil bacteria traps the atmospheric nitrogen in the forms like nitrates, nitrites and ammonia. These are radily absorbed by the plants. Hence, bacteria helps in nitrogen fixation.
