Question

bacteria convert the nitrogen in the atmosphere into__________ through the process of nitrogen fixation. non - usable nitrogen usable nitrogen n2 rewatch

Explanation:

Nitrogen fixation is the process by which bacteria convert atmospheric nitrogen ($N_2$) into forms that plants can use. Non - usable nitrogen (like $N_2$ in the atmosphere) is not directly available for most organisms. Through nitrogen fixation, bacteria convert it into usable nitrogen compounds (such as ammonia - $NH_3$).

Answer:

Usable nitrogen
