The five kingdoms

Kingdom	What they are like	Examples
animals	eat other living things and can move	dog, eagle, snail, shark
plants	make their own food with sunlight (photosynthesis)	oak, rose, fern, moss
fungi	can't make their food: many feed on dead matter	mushroom, mould, yeast
protists	tiny living things that live in water	amoeba, algae
bacteria	the smallest living things, only one cell	the bacteria in yoghurt

Fungi

Fungi are not plants: they can't make their own food.
We use yeast to make bread rise.
Some mushrooms are very poisonous: never eat wild mushrooms.

Protists and bacteria

They are microscopic: we need a microscope to see them. Algae do photosynthesis, like plants. Some bacteria make us ill, but others help us digest food or make yoghurt and cheese.

Respect all living things

Fungi and bacteria are decomposers: they break down dead matter. Every living thing has a role in its ecosystem, from the smallest bacterium to the biggest whale.
