Explanation:
Simply said, nitrogen is an essential component of numerous biomolecules including DNA, RNA, amino acids (for building proteins), many neurotransmitters are amines (nitrogen-containing molecules; R-NH2).
We get our nitrogen from the foods we eat, mostly proteins. Plants can't suck nitrogen out of the air, thus it must be absorbed from their roots in the soil, a process that is facilitated by "nitrogen-fixing" bacteria in the soil.
