When a white moth lands on a white birch tree if the birch is covered with black soot what would happen to the moth?

When a white moth lands on a soot-covered white birch tree, its camouflage is compromised. The contrast between the white moth and the black soot makes it more visible to predators. As a result, the moth is at a higher risk of being eaten compared to when it blends in with a clean white birch tree. This scenario illustrates the impact of environmental changes on the survival of species through natural selection.
