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?
a. the population will decrease
b. the population will increase
c. there will be no change in their population.
d. the population will change their food preferences.

Explanation:

The white moths relied on light tree bark for camouflage to avoid predators. When industrial soot darkened the tree bark, the white moths became highly visible to predators, making them easy targets. This increased predation will lead to a drop in their population.

A. The population will decrease
