Question

White moths were found in huge numbers in the English city of Birmingham. These moths could be easily camouflaged by the trees because white lichen covered the bark. Because of sudden industrial development, the city’s trees became covered with soot. How will this change affect the population of the white moth?

Answer 1

Answer:

The population of white moths will get decrease.

Explanation:

The techniques of camouflage used by moths save them from getting hunted by their predators. However, as the color of the bark of the trees gets changed due to the discharge of industrial population, the moths can be easily determined by their predators, and thus, their population count gets reduced due to intense hunting.

Answer 2

Ouuu I know this one, we learned a few days ago in biology. There appeared another variation of the moth, the carbonaria. It was darker in color and it is an example of temporery polymorphism. When the pollution was reduced thenumber of white moths rised again.
Sorry for my english, it is not my native language but i’m 100% sure about this
