WebAll unicellular eukaryotic creatures are classified as protists. They can be categorised as being similar to plants (autotrophs), fungus (saprotrophs), or animals (paratrophs) (heterotrophs). Protists that resemble plants carry out autotrophic photosynthesis. Protists that use photosynthetic processes include dinoflagellates, euglena, and diatoms. WebParamecia are heterotrophs because they eat other living organisms rather than using sunlight for energy as some bacteria, algae and plants do. Paramecium species simply do not have the ability to use sunlight for energy because they do not contain chlorophyll and are therefore not autotrophic.
