Living things are classified into large groups called KINGDOMS.
The three principal kingdoms are the animal kingdom, the plant kingdom and the fungi Kingdom.
Fungi are different living things from plants and animals. Many fungi are beneficial to people, but others can be harmful.
Protists include two very different types of organisms: algae and protozoa.
Algae are aquatic living things that can be unicellular or multicellular. Some multicellular marine algae can grow to a very large size. Algae are used as food in many countries, because they are very nutritious.
Protozoa are unicellular living things that live in aquatic environments. They feed on other organisms.
Monerans are unicellular living things. This kingdom includes bacteria. They are the smallest and simplest living things and can be seen through a microscope. Bacteria are everywhere in the world. They can live in all kinds of environments: soil, in water, inside other living things.
Some bacteria are helpful as those used to make yoghurt. But others are harmful like cholera.
Viruses are not included in any of the five kingdoms. They aren't living things. They can reproduce inside living things, like the flu virus.
