Answer 1

Mixotrophic nutrition:

1. Based on nutrition, organisms can be of three types: autotrophic, heterotrophic and mixotrophic.
2. Autotrophs can synthesize their nutrition on their own.
3. Heterotrophic organisms depend on others for their nutrition.
4. Some organisms can be both heterotrophs and autotrophs, which are called mixotrophs.
5. This type of nutrition is called mixotrophic nutrition.
6. For example, Euglena is called mixotrophic because in the presence of light it is autotrophic and in the absence of sunlight it becomes heterotroph.
7. Euglena belongs to the kingdom Protista.
8. Many other members of this kingdom show mixotrophic nutrition.
9. In kingdom Protista, unicellular prokaryotic organisms are included. Most of these are found in water.
10. Photosynthetic free-floating Protista is called phytoplankton and heterotrophic free-floating Protista is called zooplankton.

Final answer: Mixotrophic nutrition is exhibited by the kingdom Protista.
