Answer :
Nitrogen is not directly obtained by plants from the atmosphere. Despite being the most prevalent component in the air.
It typically takes the form of dinitrogen. Although it consists 78 percent of a atmosphere, plants cannot use it. By means of bacteria, certain algae, lightning, as well as other processes, it is absorbed into the soil. The N2 must be changed through a procedure known as nitrogen fixation for it to be utilized by plants. Fixation transforms atmospheric nitrogen into forms that plants' root systems can absorb. Following hydrogen, carbon, and oxygen, nitrogen is the fourth-most abundant element (by moles) in the living biomass. Nitrogen is necessary for life. All proteins or nucleic acids contain nitrogen because it is a component of all nucleotides and amino acids. Nitrification: The type of nitrogen that is most readily absorbed by plants is nitrate.
