Nutrients are needed by an organism to survive, grow, and reproduce. These substances are grouped as macronutrients and micronutrients. Macronutrients are named so because they are needed to be consumed in large amounts and are primarily used to generate energy or become absorbed in tissues for growth and repair. On the other hand, micronutrients are needed in small amounts. Their roles in cellular processes are not obvious.
Macronutrients include; carbohydrate, protein, and fats. While micronutrients include minerals and vitamins.
