Answer 1

Energy in foods is provided by macro-nutrients.

Step-by-step explanation:

Nutrients are “environmental substances” used for growth, energy, and bodily functions of the organisms. Those nutrients that are required in larger amounts are called macro-nutrients.

There are 3 macro-nutrients needed by humans: lipids (fats), carbohydrates (sugar) and proteins. All these macro-nutrients gives energy in form of “calories”. For example:

• In carbohydrates, there are '4 calories' of energy per gram.

• In proteins, there are '4 calories' of energy per gram.

• And in lipids, there are '9 calories' of energy in one gram.

This means that if you look at a food label and it lists 10 grams of carbohydrates, 0 grams of protein, and 0 grams of fat, that food would contain 40 calories.
