Answer:
observe the movement of the organism.
Explanation:
The movement of the two organisms under the microscope differs.
A ciliate moves by using cilia, tiny structures that beat in unison to propel ciliates in water.
Amoeba moves by using pseudopodia. The movement is crawl-like and it involves the protrusion of the pseudopodia from the cytoplasm.
Hence, observation of the movement of the organism under the microscope will give an indication whether it is a ciliate or an amoeba.
