A) is free-swimming with cilia; heterotrophic
B) is free-swimming with flagella; heterotrophic
C) is free-swimming with flagella; autotrophic
D) moves by floating in plankton; autotrophic
E) is free-swimming with cilia; autotrophic

Refer to the diagram, which shows the role of vacuoles in ciliate digestion.  The figure illustrates an experiment designed to determine whether Paramecium digests food in an acidic environment.This organism most likely _______ and is _______.
A) is free-swimming with cilia; heterotrophic 
B) is free-swimming with flagella; heterotrophic 
C) is free-swimming with flagella; autotrophic 
D) moves by floating in plankton; autotrophic 
E) is free-swimming with cilia; autotrophic

Quizplus · Accepted Answer

The diagram shows ciliates, specifically Paramecium, which are a type of free-swimming protozoan with cilia used for locomotion. The diagram also shows food being taken in by phagocytosis and moved to the vacuole for digestion, indicating that Paramecium is heterotrophic (obtains nutrients by consuming other organisms). The other answer choices are incorrect based on the information provided.
