An organism that makes its own food, typically through photosynthesis
Heterotroph meaning
An organism that obtains its food by consuming other organisms
what is Protista
Protista is a kingdom of simple, mostly single-celled eukaryotic organisms that are not plants, animals, or fungi. Examples include algae, amoebas, and paramecia.
what is single-celled meaning

Aigae
Amoebas
Paramecia
Algae
- Move using Flagella
Amoebas
- Move using pseudopodia
Paramecia
