Question

which nutrient or product provides long - term energy?
o fat
o green tea
o caffeine
o carbohydrate

Explanation:

Fat is a nutrient that serves as a long - term energy storage. When the body has excess calories, it stores them as fat. During periods of low food intake or increased energy expenditure (such as during exercise or fasting), the body breaks down fat to release energy. Green tea and caffeine are stimulants that may provide a short - term boost in alertness or metabolism but do not serve as long - term energy sources. Carbohydrates are a primary source of energy for the body, but they are used more quickly (for example, glucose from carbohydrates can be rapidly metabolized) and are not typically stored in large amounts for long - term energy compared to fat.

Answer:

fat
