Human needs nutrients like protein, vitamin, carbohydrate, fats, minerals, dietary fiber and water. All nutrients can be categorized into two groups- macronutrients and micronutrients. The difference between macronutrients and micronutrients are given below:

Macronutrients	Micronutrients
These are required in large amounts.	These are required in small amounts.
They contribute to the bulk energy needed for the metabolic system.	They help to maintain various functions of the body, growth and disease prevention.
Carbohydrates, protein, fat, fiber and water are macronutrients.	Vitamin and some minerals are micronutrients.

Conclusion

Thus, the macronutrients and micronutrients can be differentiated on the basis of their requirement, function, etc.
