Where does paramecium fall in the food chain?

Paramecium is a single-celled organism that primarily falls into the category of primary consumers in the food chain. It feeds on bacteria, small algae, and other microorganisms, thereby playing a vital role in controlling bacterial populations. In turn, paramecium can serve as a food source for larger predators, such as small protozoa and certain aquatic animals. Thus, it occupies a crucial position in freshwater ecosystems as both a consumer and a prey species.
