Correct Answer

Explanation

Paramecium lives in muddy water such as ponds and ditches and feeds on tiny microscopic like bacteria, diatoms and decayed food particles. If the two different species of Paramecium are kept in the same culture medium containing these food materials, the diagram shows that the number of Paramecium Aurelia increases with time while that of Paramecium caudatum decreases. This indicates that Paramecium aurelia is better equipped to feed on these food materials.
