Decomposition

Decomposition is when animals and plants die and their bodies break down and turn into soil by worms helping a lot. For dead animals and plants to turn into soil it needs some worms, bacteria, fungi, air, water and sun. Without worms dead animals and plants would just lie there and cover the world and wouldn't turn into soil.

When an animal or plant dies a worm will come along and eat all the good stuff out of it and poop it out to make really good fertiliser for the plants. When a Tui dies its body breaks up and a maggot eats all the soft bits and leaves the hard bits like its bones, feathers, beak, legs and head. Eventually the hard bits break up and turn into soil.
