Answer :
Final answer:
Nitrogen-fixing bacteria, such as Rhizobium, play a vital role in converting atmospheric nitrogen into forms usable by plants.
Explanation:
Nitrogen-fixing bacteria play a crucial role in transforming atmospheric nitrogen into a form usable by plants. These bacteria convert nitrogen gas into ammonia, which is further broken down into nitrogenous compounds that plants can absorb. For example, Rhizobium bacteria form a symbiotic relationship with legume plants, aiding in nitrogen fixation.
