Answer:
Light-colored moths.
Step-by-step explanation:
The process of Natural Selection, or survival of the fittest, says that only organisms with the most desireable traits will survive and reproduce. In an area with mostly light trees, dark-colored moths would have difficulty blending in with them, so they would be easily spotted and eaten by birds. If the dark moth population is reduced, only light moths will be able to reproduce, so their offspring will be light as well. Therefore, in an area with ligjt trees, light moths will evolve and be the dominant type since they can more easily hide from predators.
