“Heterotroph is an organism that is unable to synthesize its own food, and therefore, has to rely on other sources, specifically plant and animal matter.”
Types of Heterotrophic Nutrition
In nature, organisms exhibit various types of heterotrophic nutrition. They are as follows:
Holozoic Nutrition
Saprophytic Nutrition
Parasitic Nutrition
Holozoic Nutrition
Holozoic nutrition involves the ingestion and internal processing of solid and liquid food in an organism. This involves the steps of ingestion, digestion, absorption, assimilation and excretion.
Ingestion is the intake of food, which is broken down into simpler organic matters by a process called digestion. After extraction of useful components, the unwanted and undigested particles are excreted out.
Examples of animals that exhibit holozoic nutrition include all vertebrates. Even some unicellular organisms such as amoeba also exhibit holozoic nutrition
