Detailed explanation-1: -Paramecium caudatum used in this study are maintained in microcosms where they reach an average density of about 300 cells/mL.

Detailed explanation-2: -Solution. As the population of Paramoecium caudatum was grown in a culture medium. After 5 days the culture medium became overcrowded with Paramoeium and had depleted nutrients because after the overcrowding of paramoecium the nutrients became limited and got depleted. Sigmoid type of growth curve would be obtained.
