Here's why:

* Protists: This is a very diverse kingdom of eukaryotic organisms that are not animals, plants, or fungi. They are often single-celled, but some are multicellular.

* Animal characteristics: This refers to traits like heterotrophy (getting nutrients by consuming other organisms) and mobility.

* Protozoans: This group of protists are characterized by their animal-like features, including heterotrophy and the ability to move using cilia, flagella, or pseudopodia.

Some common examples of protozoans include amoebas, paramecia, and sporozoans.
