Where are protozoa typically found?

Protozoa are predominantly found in moist, watery environments due to their biological requirements for survival and reproduction. These single-celled organisms thrive in fresh and marine waters, soil that is saturated with moisture, and in decaying organic materials, as these settings provide the necessary nutrients and conditions for their metabolic processes.

In contrast, extremely dry environments, scorching hot sand, and solid rocky landscapes do not typically support the life cycles and needs of protozoa, which are reliant on water for their movement, feeding, and reproduction. Moist habitats offer ample opportunities for protozoa to feed on bacteria and organic matter, making them an integral part of aquatic and soil ecosystems.
