Protozoa (pro-to-zoh-uh) are one-cell micro-organisms.
Protozoa are something like animal.
They often spread diseases through water.
They also spread diseases through insects like malaria.
Anopheles mosquito spread malaria.
Protozoa is very important because they help to balance the ecosystem.
Protozoa are important in food chains too.
Protozoa eat algae and bacteria; then they are eaten by animals and those animals are eaten by other animals and so on until they die and eaten by bacteria and the bacteria are eaten by protozoa 🙂
