dont make their own food
Animalia and Fungi are completely heterotrophic. Some are in protozoa and monera
Protozoa are single-celled organisms that can be either heterotrophic or autotrophic. Heterotrophic protozoa feed on organic matter like bacteria, algae, and other small organisms. Autotrophic protozoa produce their own food through photosynthesis, using sunlight to generate energy.
heterotrophic - ingest food like animals
Protist may be unicellular or multicellular , they can also be heterotrophic or autotrophic. All protist are eukaryotes, which means that most of their metabolic processes occur inside their membrane-bound organelles
Protozoa are single-celled organisms that are considered animals, as they are heterotrophic and ingest their food. Algae, on the other hand, are photosynthetic organisms that can be single-celled or multicellular and are considered plant-like. Visual characteristics such as cell structure, movement, and mode of nutrition can help differentiate between protozoa and algae.

Protozoa can be classified as primary consumers, but it depends on their specific diet. Many protozoa are heterotrophic and feed on bacteria, algae, and other organic matter, making them primary consumers in some ecosystems. However, some protozoa are also predators, consuming other microorganisms, which places them higher in the food chain. Thus, while some protozoa serve as primary consumers, others fulfill different roles in their respective food webs.
Animal-like protists are heterotrophic, meaning they obtain their nutrition by ingesting organic matter or other organisms. They can be categorized as parasitic, saprophytic, or predatory depending on how they obtain their food.
PROTOZOA
While some autotrophs are categorized by some scientists as protozoans e.g., Euglena, most consider protozoans to be those single-celled organisms that are heterotrophic.
Coleps, a genus of ciliate protozoa, are primarily heterotrophic organisms. They consume bacteria, algae, and other organic matter for energy and nutrients, rather than producing their own food through photosynthesis. This distinguishes them from autotrophic organisms, which can synthesize their own food.
protozoa
If an organism is multicellular, heterotrophic (cannot make its own energy), and has no cell wall, it is an animal. This is the definition of the kingdom Animalia. There are unicellular animal-like members of the kingdom Protista commonly called protozoa. Fungi are heterotrophic and multicellular, but they have a cell wall made of chitin.
