Answer the questions below based on the video. Autotrophs are organisms which are capable of synthesizing their food themselves from organic and inorganic substances. They can be found in most aquatic environments including snow, freshwater, marine, or intrazoic habitats. The Kingdom Protista consists of eukaryotic protists. Most are found in freshwater lakes, ponds, and pools, though some inhabit brackish environments.The genus was initially described in the early 1830s by German scientist Christian Gottfried Ehrenberg, making it one of the first known groups of dinoflagellates.

Which protista are most similar to green plants? Members of this very diverse kingdom are typically unicelluar and less complex in structure than other eukaryotes.In a superficial sense, these organisms are often described based on their similarities to the other groups of eukaryotes: animals, plants, and fungi. Most euglenids are photosynthetic but can switch to a heterotrophic mode of food acquisition when light is unavailable. Identify protista as photosynthetic or heterotrophic .
