The correct answer is option 2: Symbiotic bacteria. Rhizobium is a type of bacteria that forms a symbiotic relationship with leguminous plants. This means that the bacteria and the plant benefit from each other. Rhizobium bacteria live in the root nodules of certain plants, such as peas, beans, and clover. These bacteria convert atmospheric nitrogen into a form that the plants can use, while the plants provide the bacteria with carbohydrates and an environment to live in. This mutualistic relationship is beneficial for both the bacteria and the plants involved.
