If the population of moths is found to have 100% dark colored individuals, would it be possible for them to survive if humans came and cleaned up the pollution on the trunks of the trees; returning them to a light colored bark? Why or why not?

Explain your reasoning.

Decrease occur in the population.

Explanation:

It would be impossible for dark colour moth to survive if humans cleaned up the pollution on the trunks of the trees and returning them to a light colored bark because the dark colored moths can easily be seen by their predators. The dark colour of trunk helps the dark colored moths to hide from their predators so if the black colour of the trunk are turn into light colour so there is decrease occur in the population of black colored moths.
