Answer 1

Hint: The food synthesised by the plants is in the form of carbohydrates and is stored in the form of starch. Carbohydrates are energy giving foods. Fats are also energy giving food which provides energy greater than that of carbohydrate.

Complete answer:
The nutrients present in the food are the source of energy. The metabolism of these nutrients releases energy. These nutrients are broken down into simple carbohydrates in the digestive system. The monosaccharides release energy in the form of ATP which is used up by the organism. These nutrients are carbohydrates, fats and proteins.

Carbohydrates are the instant source of energy. The food prepared by the autotrophs is in the form of carbohydrate i.e glucose. The glucose is stored in the form of starch. Some food items which are the source of carbohydrates are cereals, fruits.

The proteins are the bodybuilding food. They help in developing muscles and are also essential for the growth and repair of the body. The proteins are mainly digested in the stomach.

The fats are the energy-giving food but the energy released by the fat is greater than that of the carbohydrate. The good sources of fats include nuts, dairy products.

Let us tabulate the given food items in terms of their nutrients.

carbohydrate-rich,	protein-rich	fat-rich foods
Sweet potato, rice, maize, white bread	Moongdal, fish, milk, egg, beans, buttermilk, cottage cheese, peas	Mustard oil, butter, milk, egg, fish

Note: Some of the food items can contain more than one nutrient like milk, fish. They are the source of proteins as well as fats. The other important nutrients needed by our body are minerals like calcium, phosphorus, iodine, water and roughage and vitamins. Fruits and vegetables are rich sources of minerals, roughage and vitamins.
