The leaves would change colors and fall off if the tree is a deciduous tree
they change color and fall
They change color because of the weather change in the fall
Yes
the katydid will never survive in the fall.
Certain types of trees, known as deciduous trees, have leaves which will not survive the cold of winter, and therefore, the tree withdraws useful minerals from the leaves in the fall, so that those minerals will not be lost when the leaves die and fall off the tree. It is a process of nutritional conservation. The change in the chemical composition of the leaves causes a corresponding change in color.

It depends sometimes a leave can be yellow and next fall it can be red but usually it stays the same color every fall :)
the conclusion is that the chlorophyll is the way that how leaves change colors
Deciduous trees change the color of their leaves before they fall off in autumn.
