The form of Nutrition differs depending on type of and availability of food material as well as how it is obtained by the organism.
Heterotrophs obtain their nutrition from the other sources like plants or animals. They cannot create their own food. They do not perform photosynthesis. Except for producer all the consumers that are herbivores carnivores and omnivores are considered heterotrophs, and decomposer as well because decomposers also obtain their food from decaying organisms and natural element.
Heterotrophs are classified into 3 types
Saprotrophs – saprotrophic nutrition is that nutrition in which an organism obtain in nutrition from decaying organism matter of decayed plant and animal.
