Name the best known symbiotic nitrogen fixing bacterium isa)Nitrobacte...
N2−fixing bacteria, especially roots of legumes, can fix this atmospheric nitrogen into biologically usable forms. Nitrogen fixation requires a strong reducing agent and energy in the form of ATP. Nitrogen-fixation is accomplished with the help of nitrogenfixingmicrobes mainly rhizobium.

Rhizobium is the best known symbiotic nitrogen fixing bacterium.
Explanation:
Rhizobium is a soil bacterium that forms a symbiotic relationship with leguminous plants such as clover, soybeans, peas, and alfalfa. This bacterium is capable of converting atmospheric nitrogen into ammonia, which is then utilized by the plant.
Rhizobium forms nodules on the roots of leguminous plants, which provide a favorable environment for the bacteria to fix nitrogen. Inside the nodule, the bacteria convert atmospheric nitrogen into ammonia, which is then transported to the plant in exchange for carbohydrates.
Rhizobium is considered the best-known symbiotic nitrogen fixing bacterium because of its ability to fix atmospheric nitrogen and provide it to the plant. This process not only benefits the plant but also contributes to soil fertility, as the excess nitrogen is released into the soil and can be utilized by other plants.
Other nitrogen fixing bacteria such as Azotobactor and Nitrosomonas are also important in the nitrogen cycle, but they do not form a symbiotic relationship with plants like Rhizobium does.
