The undigested food left after the digestion of carbohydrate rich foods are usually left behind as fecal matter, whereas the nutritious bacteria grow and spread in the environment causing no harm to the body. Some of the important prebiotics are acidophilus, bifidus, and Clostridium. These bacteria are called heterotrophic nutrition. Many of the species of plant eat the carbohydrates present in these foods, and therefore, heterotrophic nutrition is very essential for plant growth.
