Solution(By Examveda Team)

A micronutrient is required in very small amounts but is as important as a major element.
Micronutrients are essential dietary elements required by organisms in varying quantities throughout life to orchestrate a range of physiological functions to maintain growth and development.
There are about seven nutrients essential to plant growth and health that are only needed in very small quantities, and these are Boron, chlorine, copper, Iron, Manganese, Molybdenum and Zinc.
