Reproduction and Life Cycle
Paramecium reproduces primarily through asexual reproduction (binary fission), where the organism divides longitudinally into two identical daughter cells. Under optimal conditions, Paramecium can reproduce rapidly, contributing to its abundance in freshwater habitats.

Conjugation: In response to environmental stress or scarcity of food, Paramecium can undergo conjugation—a form of sexual reproduction where genetic material is exchanged between two individuals. This process promotes genetic diversity and enhances survival in changing environments.
Ecological Significance
Paramecium plays a crucial role in freshwater ecosystems:
Food Source: As a primary consumer, Paramecium helps regulate bacterial and algal populations, contributing to nutrient cycling and ecosystem stability.
Indicator Species: The presence and abundance of Paramecium can indicate water quality. Its sensitivity to pollutants and environmental changes make it a valuable bioindicator for assessing freshwater health.
