Detailed explanation-1: -Legumes are able to form a symbiotic relationship with nitrogen-fixing soil bacteria called rhizobia. The result of this symbiosis is to form nodules on the plant root, within which the bacteria can convert atmospheric nitrogen into ammonia that can be used by the plant.

Detailed explanation-2: -Successful Rhizobium-legume symbioses will definitely increase the incorporation of BNF into soil ecosystems. Rhizobium-legume symbioses are the primary source of fixed nitrogen in land-based systems (313) and can provide well over half of the biological source of fixed nitrogen (313).

Detailed explanation-3: -Nitrogen is produced in nodules that form on the roots of legumes, which contain Rhizobium bacteria. The bacteria take nitrogen from the air and convert it into a form the plants can use. When legumes are pulled up in the fall, excess nitrogen from the nodules is left in the soil.

Detailed explanation-4: -This biochemical reaction takes place in the root nodules formed by rhizobia bacteria. Rhizobia bacteria convert nitrogen gas (N2) into ammonia (NH3), and the legume plant provides the bacteria with carbohydrates as an energy source.

Detailed explanation-5: -Housed within specialized organs, called nodules, on the roots of legume plants, rhizobia fix atmospheric N2 via the enzyme nitrogenase to produce ammonia and provide it to the plant in return for reduced carbon generated via photosynthesis.
