The correct Answer is:
To determine which element is not a trace element or micronutrient, we can follow these steps: 1. **Understand the Categories of Nutrients**: - There are 17 essential elements for plants, which are divided into two categories: macronutrients and micronutrients (or trace elements). - Macronutrients are required in larger quantities, while micronutrients are needed in smaller amounts. 2. **Identify the Macronutrients**: - The macronutrients include: - Carbon (C) - Hydrogen (H) - Oxygen (O) - Nitrogen (N) - Phosphorus (P) - Potassium (K) - Calcium (Ca) - Magnesium (Mg) - Sulfur (S) 3. **Identify the Micronutrients**: - The micronutrients (or trace elements) include: - Iron (Fe) - Manganese (Mn) - Copper (Cu) - Zinc (Zn) - Boron (B) - Molybdenum (Mo) - Chlorine (Cl) - Nickel (Ni) 4. **Analyze the Options Given**: - From the question, we need to identify which of the provided options is a macronutrient. - Among the options, if Potassium (K) is listed, we recognize it as a macronutrient. 5. **Conclusion**: - Since Potassium is a macronutrient, it is not a trace element or micronutrient. Therefore, the answer to the question is Potassium. **Final Answer**: Potassium is not a trace element/micronutrient. ---
