As plants receive less sunlight, they change color. They are green because they have a lot of sunlight and are able to produce glucose and other energy chemicals. The less sunlight they receive, the less chemicals they produce.
These are chemical changes.
Drying of leaves is a physical change because neither it changes its composition nor does it have any different properties from the original one.

It is amazing to watch nature change seasons, so many different colors appear in each season. Leaves change colors in fall because many of the leaves are dying.
It is a chemical change anytime you burn something it will most likely be chemical change because something new comes out, for example when you burn the leaves you will get ash which is something the leaves did not have before! your welcome!:)

No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.

Burning leaves would be a chemical change because once the leaves are burnt, you can't turn the ashes back into leaves.
