Question

Are all protists heterotrophs?

Answer 1

Protists:

1. Protists are eukaryotic, unicellular organisms that belong to the kingdom Protista.
2. All protists are not heterotrophs. They can be autotrophs, heterotrophs, or mixotrophs.
3. Autotrophic protists possess chlorophyll that helps them in photosynthesis. Example: giant kelp, sea lettuce.
4. Protists that depend on other living things for nutrition are called heterotrophs. They can be predators or parasites. Example: Amoeba, Plasmodium.
5. Mixotrophic protists can act as both autotrophs and heterotrophs. Example: Euglena.
