Bacterial action, along with fungi and other microorganisms, is responsible for the decomposition of organic matter. Vegetable remains (A), animal carcasses (C), and wastes of flowers (D) are all composed of organic materials that are readily biodegradable by bacteria and other decomposers in the environment. Plastic materials (B), on the other hand, are typically synthetic polymers derived from petroleum. Their complex chemical structure makes them resistant to breakdown by most common bacteria and natural decomposition processes, leading to their persistence in the environment.
