Explanation:

This question is incomplete because of the absence of options. However, there are some general terms that should indicate the answer. This question also seem to focus on the classes of food and food in general, thus the answers should be related to food.

(a) Calcium is mineral needed in the body to make bones and teeth stronger.

(b) There are two broad types of nutrients; they are micronutrients and macronutrients. Micronutrents are those nutrients that the body needs in little amount/quantity (examples are vitamins and minerals) while macronutrients are nutrients that the body requires in large quantity (examples are carbohydrates, proteins, and lipids)

(c) Iron is a mineral that assists in blood production in the body.

(d) Oil and butter are good sources of lipids in the body.

(e) More water/glucose is required for people who do a lot of physical work. Water helps transport nutrients around the body which helps to produce energy (that is needed after an exercise); an individual exercising loses water through sweat and will need to gain this water back by drinking. While glucose break-down leads to the production of energy. This is the reason water or glucose is needed more by an individual who do a lot more physical work.
