Question

Why do leaves turn red and shed off during the autumn season?

Answer 1

Leaves turn red and shed off during the autumn season:

1. When the temperatures in the autumn season begin to drop, the air becomes colder.
2. During this season, the amount of sunshine falls and the production of the chlorophyll pigment in the leaves decreases until it completely stops.
3. Consequently, the leaves change to a yellow or red color.
4. Subsequently, the leaves dry out and fall because of a lack of color.
5. As a result, throughout the autumn season, leaves turn red and drop off.
