Answer: a complex carbohydrate made of many glucose molecules is known as a polysaccharide.
Explanation: these molecules are composed of multiple sugar units linked together forming a layer-like linkage and are more intricate structures compared to simple carbohydrates like glucose or sucrose. polysaccharides serve as important sources of energy and storage in various biological segments. examples like starch in plants and glycogen in animals, both of which play essential roles in providing sustained energy reserves in animals in muscles, ready to be broken down into glucose when needed.
so, hence explained that polysaccharides are complex structures that enable themselves to evolve energy in living beings.
