Chapter 26, Problem 10TYU
Summary Introduction
Introduction: Cellular slime molds are protists where the independent organization of cells forms an aggregate. They act independently of each other during the growth phase. These organisms have been classified as unikonts due to similarities between these groups, unlike other eukaryotes.

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.
