Magnesium

Vedclass · Answer

(B) The correct answer is $B$. Macronutrients are essential elements present in plant tissues in large amounts,typically $1-10 \ mg$ per gram of dry weight. These include carbon,hydrogen,oxygen,nitrogen,phosphorus,sulfur,potassium,calcium,and magnesium. Micronutrients,or trace elements,are required in very small amounts,typically equal to or less than $0.1 \ mg$ per gram of dry matter. These include iron,manganese,copper,molybdenum,zinc,boron,chlorine,and nickel. Since magnesium is a macronutrient,it is not a micronutrient.
