Solution(By Examveda Team)

Nitrogen is a major nutrient because it is required by plants more.
Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide.
It is also a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.
