Question

4. Why do leaves change colors in the fall?

Answer 1

Answer:

The pigment that causes leaves to be green is chlorophyll. Chlorophyll is important for plants to make food using sunlight. ... As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall.

Explanation:

In autumn when it starts to get cold, some plants stop making chlorophyll. Instead, those plants break down chlorophyll into smaller molecules. As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall.
