why do the colors on the leaves change in the fall?

Answer 1

The colors of the leaves you see in the fall are the natural colors of the leaves. It's the chlorophyll in the leaves that makes them green. Chlorophyll is the chemical that allows plants to convert sunlight to energy, keeping them alive. While alive and healthy, the volume of this chemical (which is green in color) makes the leaves look green. When the plants start to die (or "hibernate" for the winter), the volume of chlorophyll drops considerably, allowing the leaves to take on their natural colors.

Answer 3

Most trees are envious of chameleons and have tried for centuries to become like them. Some trees evolved in areas with brown soil, so their leaves change to brown so that when they fall to the ground they will be hidden. Some have leaves that turn red to match the clay. Others have leaves that turn yellow to match the stone cliffs. It is all pretty obvious.

Answer 4

Here's the odd thing-- they actually don't. What happens is, with less sunlight, the leaves stop producing chlorophyll which usually hides the tree's natural color.

Answer 5

because trees make chlorophyll which is what keeps the leaves green but in the winter the trees stop making it to store up for the winter in order to come back in spring, and then the tree appears dead.
