Heterotrophic

Members of the kingdom Animalia exhibit a heterotrophic mode of nutrition i.e., they depend upon other organisms for food.


Holozoic

• Internalisation (ingestion of food) and internal digestion of liquids or solid food components characterise holozoic nutrition.
• Members of kingdom Animalia ingest food as a whole and digest it within their bodies.

Saprophytic

• Saprophytic/Saprotrophic animals feed on dead and decayed organic matter.
• For example, Pheretima (earthworms) derive nutrition from decaying organic matter.
