(D) The essential mineral elements are classified into two categories based on their quantitative requirements by plants:$1$. Macro-nutrients: These are required in large amounts (e.g., $C, H, O, N, P, K, S, Ca, Mg$).$2$. Micro-nutrients or trace elements: These are required in very small amounts (e.g., $Fe, Mn, Cu, Mo, Zn, B, Cl, Ni$).Calcium $(Ca)$ is a macro-nutrient because it is required by plants in concentrations greater than $10 	ext{ mmol kg}^{-1}$ of dry matter. Therefore, it is not a micro-nutrient.
