Vedclass · Answer

(D) Macronutrients are essential elements required by plants in large amounts (generally $10 	ext{ mmol kg}^{-1}$ of dry matter).These include Carbon $(C)$, Hydrogen $(H)$, Oxygen $(O)$, Nitrogen $(N)$, Phosphorus $(P)$, Sulphur $(S)$, Potassium $(K)$, Calcium $(Ca)$, and Magnesium $(Mg)$.Micronutrients are required in very small amounts (less than $10 	ext{ mmol kg}^{-1}$ of dry matter).These include Iron $(Fe)$, Manganese $(Mn)$, Copper $(Cu)$, Molybdenum $(Mo)$, Zinc $(Zn)$, Boron $(B)$, Chlorine $(Cl)$, and Nickel $(Ni)$.In option $D$, Zinc $(Zn)$, Boron $(B)$, and Chlorine $(Cl)$ are all micronutrients, not macronutrients.
