Question

why do leaves change their colour​

Answer 1

Answer:

due to the hormones present in them they star ageing or if they are in deficiency of any mineral

Answer 2

As summer fades into fall, the days start getting shorter and there is less sunlight. This is a signal for the leaf to prepare for winter and to stop making chlorophyll. Once this happens, the green color starts to fade and the reds, oranges, and yellows become visible.
