EVERYDAY SCIENCE

Detailed explanation-1: -To be used by plants, the N2 must be transformed through a process called nitrogen fixation. Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems.

Detailed explanation-2: - Specialized bacteria can convert nitrogen from the atmosphere into a form that plants can use. This process is called biological nitrogen fixation (BNF). Through a symbiotic relationship with legume plants, rhizobia provide the plant with “fixed” nitrogen, which the plant uses for its growth.

Detailed explanation-3: -Nitrogen fixation in nature Nitrogen is fixed, or combined, in nature as nitric oxide by lightning and ultraviolet rays, but more significant amounts of nitrogen are fixed as ammonia, nitrites, and nitrates by soil microorganisms. More than 90 percent of all nitrogen fixation is effected by them.

Detailed explanation-4: -Biological nitrogen fixation or diazotrophy is an important microbe-mediated process that converts dinitrogen (N2) gas to ammonia (NH3) using the nitrogenase protein complex (Nif).
