Protozoa are single-celled organisms that belong to the kingdom Protista. They are microscopic in size and can be found in various habitats such as freshwater, marine environments, and even in the bodies of other organisms.
These organisms are known for their diverse shapes and sizes, as well as their ability to move using structures like cilia, flagella, or pseudopods. Some protozoa are parasitic and can cause diseases in humans and animals.
Despite their small size, protozoa play a crucial role in ecosystems as they are important predators and prey in the food chain. They also contribute to the decomposition of organic matter, helping to recycle nutrients in the environment.
Overall, protozoa are fascinating organisms that have a significant impact on the natural world and are essential for maintaining ecological balance.
