Which one of the following is a micro element?
Show Hint
- Nitrogen
- Magnesium
- Sulphur
- Manganese
The Correct Option is A
Solution and Explanation
Nitrogen (N) is actually a macronutrient, required in large quantities by plants.
Microelements are nutrients needed in small amounts, such as Manganese (Mn), Iron (Fe), Zinc (Zn), and Copper (Cu).
Magnesium (Mg) and Sulphur (S) are also macronutrients.
Therefore, Nitrogen is not a microelement, so this is a tricky question.
