Protists are a group of eukaryotic organisms that are brought together by scientists mostly by convenience. I) What is the relationship between all protists that ties them together? ii) provide an example of a autotrophic and heterotrophic protists group, iii) what is the relationship between the multicellular eukaryotes and the protists?
In the early 1930s, G. F. Gause carried out a series of experiments using two species of ciliated protists (Paramecium), which are single-celled eukaryotic protozoans. The protists were cultured together and separately, with the bacteria being the single food source. The results are shown in the figure below. (a) Based on figure, identify and explain the interaction that is taking place between P. caudatum and P. aurelia. (b) Clam shrimp, a natural predator to P. caudatum, is introduced to the culture containing both P. caudatum and P. aurelia after 24 days. Predict the impact that the clam shrimp will have on the culture and the populations. Justify your prediction.

Group of answer choices Some protists are mixotrophic Certain protists share a common ancestor with land plants Some protists are photosynthetic prokaryotes which are similar to the ancestral chloroplast Protists are a polyphyletic group of organisms that often bear little resemblance to each other Although most protists are unicellular, some protists are multicellular as well
