Question

why is a protozoan considered animal - like?
it is a heterotroph.
it is multicellular.
it has a flagellum.
it has a cell wall.

Explanation:

Animal - like protists (protozoans) are heterotrophs. Heterotrophs are organisms that cannot produce their own food and rely on other sources for nutrition, which is a characteristic similar to animals.
Protozoans are unicellular, not multicellular. Many organisms other than protozoans (e.g., some bacteria) can have flagella. Plant - like protists have cell walls, while animal - like protists (protozoans) do not have cell walls.

Answer:

It is a heterotroph.
