sample B and explain the comparison. P : Energy content in sample A is higher than sample B. P : A contains lipid while B contains carbohydrate. P : Lipid have two times higher energy content compare to carbohydrate Able to suggest two examples of food samples which have similar energy value to food sample B and the reasons. Sample answer: P : Rice, bread or any two foods contain carbohydrate. P : Because it contain carbohydrate.
