<human>:  What is the difference between a macronutrient and a micronutrient?
<bot>: The difference between a macronutrient and a micronutrient is that macronutrients are nutrients your body needs in large amounts; they provide the bulk of your energy, such as carbohydrates, proteins, and fats. Micronutrients, on the other hand, are needed in much smaller amounts and are essential for the proper functioning of your body systems, such as vitamins, minerals, and enzymes.
