FACTS ABOUT TREE LEAVES
Trees are busy during Spring and Summer soaking up sun, water and oxygen.
They use these three items to make their own food and to make Chlorophyll.
The Chlorophyll coats their leaves with green, all Spring and Summer.
But in the Fall, the weather changes; the days are shorter with less sunshine and the days are dryer with less water.
Soon the tree does not have enough sun and water to make both it's food and Chlorophyll, so it stops making Chlorophyll and the leaves return to its natural color.
 

SEE THE BUSY TREE

See the busy tree - out in the sun,
Soaking up rays -  and oxygen.

See the trees roots – how they grow down,
They’re soaking up water – from the ground.

Using these three elements – and making them just so,
The tree makes its own food – so that it can grow.

But when it has extra – oxygen, water and sun
It also makes Chlorophyll – just for fun.

It coats its leaves with Chlorophyll – so now they all - green.
And all through the summer, - they have a lovely sheen.

But when the days grow shorter – and the earth begins to dry,
All the things the tree needs – are now in short supply.

So the tree stops making – Chlorophyll at all
And then the leaves return - to their own color - in the Fall.
