The peppered moth population in a locality has light and dark moth varieties. the tree barks in the locality are covered with light-colored lichens. how would the population of the two moth varieties change over time?

Why do leaves change color in the fall? green pigments break down and no longer mask the color of chlorophyll. chlorophyll breaks down and no longer masks the colors of other pigments. red- and yellow-colored pigments grow and mask green-colored chlorophyll. green-colored chlorophyll breaks down and turns red and yellow.
