Final answer:
Starch is produced by plants, glycogen is produced by animals, cellulose is produced by plants, and chitin is produced by fungi.
Step-by-step explanation:
Starch is produced by plants and is their primary energy storage molecule. It is composed of glucose units and is found in plant parts such as roots and seeds.
Glycogen, on the other hand, is produced by animals and bacteria as their energy storage molecule. It is structurally similar to starch and is found in the liver and muscles of animals.
Cellulose is primarily produced by plants and is a major component of their cell walls. It provides structural support and is not easily digested by most animals.
Chitin, which is another polysaccharide, is primarily produced by fungi and also some animals. It is found in the exoskeleton of arthropods and the cell walls of fungi.
