Why do the leafs turn color in the fall
It's been a while, so ... There are different pigments in all leaves. (Pigments are like dyes. They give leaves their color.) Chlorophyll is one and it is green and it is by far the most common. It hides the other pigments. Chlorophyll captures sunlight and turns it into energy so the plant can grow, but is used up while it does this. As long as there is plenty of sunlight (Spring, summer, and early fall) the chlorophyll is replaced as fast as it is used up, so leaves stay green. In late fall the number of hours of light gets less and so there is less and less replacement chlorophyll produced. That allows the other pigments to show through. And those are what we see in the fall foliage. Hope this helped.
Because the season is changing and it gets a little cold for the plants. When the weather change the leaves change colors and fall off the tree.
The leafs die so the pigment changes color and the leaf falls off
