Producers are the group of organisms that produce their own food by harnessing the sunlight and other raw materials from the physical environment. The organisms that cannot produce their own food by using raw materials from the environment are called consumers. Consumers are of five types. They are Herbivore, carnivore, omnivore, detritivores, and decomposers. Therefore, all the three choices carnivore, omnivore, and detritivores are the consumers. Hence, the others options (a), (b), (c), and (d) are incorrect.
Therefore, the correct answer is option (e) I, II, and III.
