Step-by-step explanation:
Complex carbohydrates, or polysaccharides, consist of hundreds or even thousands of monosaccharides. They include starch, glycogen, cellulose, and chitin. They generally either store energy or form structures, such as cell walls, in living things. Starch is a complex carbohydrate that is made by plants to store energy. Glycogen is a complex carbohydrate that is made by animals and fungi to store energy.
