1: indispensable to body function

2: required to prevent deficiency diseases

3: a caloric nutrient

5: required in small quantities

Answer: 3: a caloric nutrient

Vitamins are the organic compounds needed for different physiological actions which can only be got from diet as they cannot be produced in the body as prescribed levels. Vitamins represents calorie nutrients in the sense that they are not an energy source nor do they possess calories. Caloric nutrients are known as the macronutrients like carbohydrates, proteins, and fats, the regardless of the daily diet calories come from them. Vitamins are very small in size, are vital for body functioning and in the absence of these may give rise to diseases. While caloric nutrients are the ones that generate energy for the body, vitamins, on the other hand, are not edible building blocks, but rather work as enzymes or regulating agents in the body’s metabolic processes.
