Question 5: Describe how carbohydrates are stored in the body for energy.

Answer: Fats are the most calorific, providing approximately 9 calories per gram.

Question 7: Draw a simple diagram showing how the three macronutrients contribute to a balanced diet. Label each section clearly.

Question 9: Sketch a plate divided into sections to show a typical balanced meal, indicating where each macronutrient might be found.

Answer: A plate with sections labeled: one for carbohydrates (e.g., rice or potatoes), one for proteins (e.g., chicken or beans), and one for fats (e.g., avocado or oil), with appropriate proportion sizes.
