Which of the following pair type of nutrient - nutrient is correct?
I. Macronutrient - Iron
II. Micronutrient - Calcium
Answer & explanation
Correct answer: option 4
The correct answer is Option (4)- Only II
Plants rely on nutrients to support their vital physiological processes, which can be classified into macro and micronutrients.
- Iron is considered a micronutrient because plants require it in relatively small quantities compared to macronutrients. Therefore, the pairing of iron with macronutrient is incorrect.
- Calcium, on the other hand, is categorized as a macronutrient due to its critical roles in both the structure and function of plants. Consequently, the pairing of calcium with micronutrient is inaccurate.
