Hints & Solution
(b) Magnesium is a macronutrient. Micronutrients are essential elements that are required by plants in small amounts. They include $Fe, Cu, B, Mo, Mn, Cl$, and $Ni$. Macronutrients, on the other hand, are those essential elements that are required by plants in larger amounts. The examples include $C, H$, $O, N, S, P, K, Ca$ and $Mg$.
