Protists live in almost any environment that contains liquid water. Many protists, such as algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton.ost eukaryotic algae are autotrophic, but the pigments were lost in some groups. Other protists are heterotrophic, and may present phagotrophy, osmotrophy, saprotrophy or parasitism. Some are mixotrophic. Many protists are flagellate, for example, and filter feeding can take place where the flagella find prey.
1 A characteristic of red algae is that their plastids contain only one type of chlorophyll -- chlorophyll a. 2  This is different from Green algae and plants which have both chlorophyll a and b. 3  Dinoflagellates these evolved on a separate line that includes, surprisingly, the ciliated protists.
