Which of the following is an example of holozoic nutrition.

• It is a type of nutrition that entails ingesting a variety of complex organic molecules, some of which may be in a solid or liquid form. 
• The digestive system's enzymes subsequently break down the complex food into simpler ingredients. Ingestion, digestion, absorption, assimilation, and egestion are the steps of holozoic nutrition.

1. Holozoic feeding is therefore a heterotrophic style of nourishment for humans.  Amoeba, humans, dogs, cats, and other organisms are other examples of holozoic feeding.
2. Fungi - Fungi eat in a saprophytic manner. They obtain their nourishment from living or decomposing organic materials. Enzymes are released to convert complicated organic materials into simpler forms.
3. Bacteria - Based on how they obtain their nutrients, bacteria can either be autotrophic or heterotrophic. Additionally, there are two forms of autotrophic: photoautotrophic and chemoautotrophic. Additionally, there are two forms of heterotrophic: photoheterotrophic and chemoheterotrophic.
4. Virus - Viruses are kept between live things and inanimate objects. They are natural and inert. In order to complete their life cycle, viruses need a host. To reproduce, this virus needs live cells.
5. A kind of heterotrophic feeding known as holozoic nutrition is characterized by the internalization and processing of food particles that are gaseous, liquid, or solid.

Hence, option A is the correct answer.
