Question

What is noun form of the adjective 'holozoic'?​

Answer 1

Answer:

Holozoic nutrition (Greek: holo-whole ; zoikos-of animals) is a type of heterotrophic nutrition that is characterized by the internalization (ingestion) and internal processing of gaseous, liquids or solid food particles.[1] Protozoa, such as amoebas, and most of the free living animals, such as humans, exhibit this type of nutrition where food is taken into the body as a liquid or solid and then further broken down is called holozoic nutrition. Most animals exhibit this kind of nutrition.



Amoeba, Entamoeba histolytica uses holozoic nutrition.

In Holozoic nutrition the energy and organic building blocks are obtained by ingesting and then digesting other organisms or pieces of other organisms, including blood and decaying organic matter. This contrasts with holophytic nutrition, in which energy and organic building blocks are obtained through photosynthesis or chemosynthesis, and with saprozoic nutrition, in which digestive enzymes are released externally and the resulting monomers (small organic molecules) are absorbed directly from the environment.

There are several stages of holozoic nutrition, which often occur in separate compartments within an organism (such as the stomach and intestines):

Ingestion: In animals, this is merely taking food in through the mouth. In protozoa, this most commonly occurs through phagocytosis.

Digestion: The physical breakdown of complex large and organic food particles and the enzymatic breakdown of complex organic compounds into small, simple molecules.

Absorption: The active and passive transport of the chemical products of digestion out of the food-containing compartment and into the body or cytoplasm.

Assimilation: Utilization of the absorbed molecules for various metabolic processes.

Egestion: The expulsion of undigested material, commonly called defecating
