Holozoic Nutrition
It is a type of heterotrophic nutrition in which complex food is consumed by the body and processed internally. Simple nutrients are absorbed by the body after digestion, whereas undigested substances are expelled from the body. Most vertebrate species as well as single-celled creatures like Paramecium and Amoeba exhibit this style of nourishment.
Types of Holozoic Organisms
Holozoic nutrition is observed in these three types of organisms:-
- Herbivores: The animals that are directly dependent on plants for their nutrition are called Herbivores. E.g. Zooplankton, Deer, Cow, etc.
- Carnivores: The animals that feed on other animals are called Carnivores. E.g. Lion, Tiger, Shark, etc.
- Omnivores: The animals that feed on both plants and animals are called Omnivores. E.g. Humans, Rats, etc.
Heterotrophic Nutrition
Heterotrophic mode of nutrition is most commonly seen in humans. Nutrition is broadly classified into two types- Autotrophic nutrition and Heterotrophic nutrition. In heterotrophic nutrition, the organism obtains and uses organic nutrients from other species. All the organisms belonging to Kingdom Fungi and Kingdom Animalia show completely heterotrophic nutrition. Organisms of Kingdom Plantae show a completely autotrophic type of nutrition, except for some parasitic, symbiotic, and partially heterotrophic plants.
