why autumn leaves change

Changing of autumn leaves


Autumn leaves change colors because of pigments hidden in the chlorophyll. Chlorophyll is a chemical collects sunlight and turns it into energy for the tree. The tree stores the energy for the winter and the leaves no longer need to collect sunlight, so the chlorophyll isn’t made anymore so you can see the pigments. Later because of their being no more chlorophyll the leaves don’t have a job and they fall.
