Video summary
Broadleaf trees lose their leaves in autumn in preparation for winter.
Chlorophyll is the green chemical that captures the sunlight and this breaks down in autumn, showing the other colours underneath.
The leaves fall, thousands of tons of them and three members of a demolition squad break them down.
The first are the earthworms which eat through the leaves and mix them into remains into the soil.
The second group are the fungi which break down the leaves and live off their nutrients.
In the autumn the fungi grow caps which make spores carried by the wind and these spores will grow into new fungi.
The final group are the slime moulds which can gang up together and form a carpet.
They move around the woodland floor, eating the rotting leaves.
When they have eaten all the food they too can make spores which will one day grow into new slime moulds.

Teacher Notes
As a starting point pupils could list the similarities and differences between the life cycle of the fungi and slime mould.
This clip will be relevant for teaching Science/ Geography.
This topic is suitable for KS1 and KS2 in England and Wales and in Northern Ireland. Also Early and 1st Level in Scotland.
