The material states that carbon, nitrogen, iron and copper are macro nutrients found in plants.

The material states that carbon, nitrogen, iron and copper are macro nutrients found in plants.

• A. True
• B. False
• C. They are micro nutrients
• D. Macro nutrients are only minerals from the soil

Answer: (C)

Plants categorize nutrients by how much they require: macronutrients in large amounts and micronutrients in trace amounts. The typical macronutrients are carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Iron and copper, on the other hand, are micronutrients. Saying that carbon, nitrogen, iron, and copper are all macro nutrients mixes two groups, which isn’t accurate. So the statement is not correct because iron and copper belong to the micronutrient category, while carbon and nitrogen are macronutrients.
