Question 1 Report

Which of the following groups contains only macro-nutrients?
Answer Details
The group that contains only macronutrients is calcium, magnesium, and potassium. Macronutrients are nutrients that are required in large amounts by plants for growth and development. Calcium, magnesium, and potassium are all essential macronutrients that play important roles in plant growth, such as structural development, photosynthesis, and nutrient uptake. Phosphorus, nitrogen, molybdenum, manganese, copper, zinc, boron, and sulfur are also important nutrients for plant growth, but they are required in smaller amounts and are therefore classified as micronutrients.
