Question

Zn, Cu, Fe and Mo are examples of

• A. Macronutrients
• B. Non-essential elements
• C. Trace elements
• D. None of the above

Answer 1

The correct option is C Trace elements

The nutrients that are required in greater quantities are called macronutrients and those elements that are required in smaller quantities are called trace elements or micronutrients.

Macronutrients: $N,K,Ca,Mg,P,$ and $S$

Micronutrients: $Cl,Fe,B,Mn,Zn,Cu,Mo,$ and $Ni$

Micronutrients, since they are required in very little quantity are then often called 'Trace elements'.

Thus, the correct answer is option (C).
