Which type of nutrients primarily provides energy for animals?

1. Proteins

2. Carbohydrates

3. Vitamins

4. Minerals

The correct answer is: Carbohydrates

Carbohydrates are the primary source of energy for animals. They are composed of carbon, hydrogen, and oxygen, and can be quickly metabolized to release glucose—the fundamental energy currency for cells. When animals consume carbohydrates, their digestive systems break them down into simple sugars, which are then absorbed into the bloodstream and used by the body for energy. While proteins can also provide energy, their primary role is to build and repair tissues, and they are typically utilized for energy only when carbohydrate sources are low. Vitamins and minerals, on the other hand, serve essential roles in various metabolic processes and the overall health of animals but do not provide energy in the form of calories.
