Solution(By Examveda Team)

Non-essential mineral nutrients (elements) are required by certain plants, but not all, to perform their metabolic activities. The non-essential plant elements include hydrogen, oxygen and carbon.
Essential nutrients are those that cannot be synthesized by the human body, hence they need to be absorbed from outside whereas, non-essential nutrients are those that can be synthesized by internal processes.
