Living things need air to perform the chemical process that releases energy from food. Living things need water so the body does not dehydrate. You need water to properly function. Living things need food because food supplies the raw materials that are necessary to carry on the life process. Your body uses the nutrients from the food to replace cells and also as an energy source.
