Micronutrients are required in what relative amounts compared with macronutrients?

• A. They are required in larger amounts than macronutrients.
• B. They are required in smaller amounts than macronutrients.
• C. They are not required in the diet.
• D. They only provide energy.

Answer: (B)

Micronutrients are required in smaller amounts than macronutrients. Macros—carbohydrates, proteins, and fats—are needed in larger, gram-level quantities and provide the bulk of energy for the body. Micronutrients, including vitamins and minerals, are needed in much smaller amounts (micrograms to milligrams) but are essential because they act as cofactors and catalysts in metabolic processes that convert macronutrients into usable energy and support growth, immunity, and overall function. They do not provide calories themselves, but without them, energy production and many other bodily processes can falter. So the correct idea is that micronutrients are required in smaller amounts compared with macronutrients.
