Explanation:

1. Macronutrients (carbs, fats, proteins) supply energy and are required in large daily quantities, unlike micronutrients which are needed in small amounts.
2. Carbohydrates are the body's primary quick energy source as they are broken down rapidly for fuel.
3. During digestion, carbohydrates are enzymatically broken down into glucose, the main usable form of sugar for cells.
4. Glycogen, the stored form of glucose, is kept in the liver (to regulate blood sugar) and muscles (for local energy use).
5. Simple carbohydrates are made of one/two sugar molecules; candy is high in refined simple sugars, while the other options are complex carbs.
6. Complex carbohydrates are made of long sugar chains; whole grains retain their fibrous, nutrient-dense structure, unlike the refined or simple sugar options.
