Q
Q: Which of the following is NOT a macronutrient essential for plant growth?
Solution: Iron is a micronutrient, while nitrogen, phosphorus, and potassium are macronutrients.
Steps: 5
Step 1: Understand what macronutrients are. Macronutrients are nutrients that plants need in large amounts to grow.
Step 2: Identify the common macronutrients for plants. The main macronutrients are nitrogen, phosphorus, and potassium.
Step 3: Know what micronutrients are. Micronutrients are nutrients that plants need in smaller amounts.
Step 4: Identify iron as a nutrient. Iron is a nutrient that plants need, but only in small amounts.
Step 5: Determine which nutrients are macronutrients and which are micronutrients. Since nitrogen, phosphorus, and potassium are macronutrients, and iron is a micronutrient, iron is NOT a macronutrient essential for plant growth.
