why does leaves change colour at fall

Answer 1

Hello

The answer is

There are pigments present on the surface of leaves called chlorophyll. During the fall, chlorophyll breaks down.

The chlorophyll breaks down and the green colour dissappears and different colors mainly like yellow to orange becomes visible and give the leaves part of their fall splendor.
