Question

During the industrial revolution in England, a population of light-colored moths population fell while a population of dark-colored moths population rose. Both types of moths were usually found on the trunks of trees in cities.
Apparently, birds were eating the light-colored moths at a faster rate than they could reproduce. But they were leaving many of the dark-colored moths alone. What is the BEST explanation for this data?




a

The trees had become coated with soot and the dark moths were better camouflaged.

b

Dark-colored moths flew faster than light-colored moths.

c

The birds' vision had become impaired.

d

The white moths had become tastier.

Answer 1

Answer:

A

Explanation:

The darker moths would be harder for the bird to see due to the amount of soot on the trees. The darker moth population would thrive and continue to grow, while the lighter colored moth population would decrease.
