Definition

  • Most animals, including humans, have a holozoic mode of nutrition.
  • Protozoa like amoebas are holozoic, engulfing food particles through phagocytosis.

Advanced Usage

• Scientific Context: The term is primarily used in biology, particularly in ecology, physiology, and taxonomy, to classify and describe nutritional strategies.
  • The distinction between holozoic, saprophytic, and parasitic nutrition is fundamental in microbiology.

Variants and Related Words
