Read this paragraph and answer the question.
During photosynthesis, “producers” like green plants, algae, and some bacteria convert light energy from the sun into chemical energy. Photosynthesis produces chemical energy in the form of glucose, a carbohydrate or sugar. The glucose produced by photosynthesis is an integral part of the food chain because a great deal of energy is stored in the chemical bonds in the glucose molecule, and this energy can be released during digestion and chemical processing by other organisms.
