Explanation:

Plants obtain nitrogen through a natural process. ... Bacteria in the soil convert the nitrogen to ammonium and nitrate, which is taken up by the plants by a process of nitrogen fixation. All plants need nitrogen to make amino acids, proteins and DNA, but the nitrogen in the atmosphere is not in a form that they can use.

Answer 2

Plants need nitrogen to make proteins . As the plants can't take atmospheric nitrogen directly from air , they obtain it with the help of bacterias present in the soil .
