White moths were found in huge numbers in the city of birmingham. these moths could be easily camouflaged by the trees. because of sudden industrial development, the trees in the city were covered with soot. how will this change affect the population of white moths?

The soot is blackish in color and are produced due to the partial burning of different types of organic matters.  

According to the given condition, the soot is released because of the sudden development of industries. As a result of which this soot is released into the atmosphere and the trees in the city were covered with this soot. Due to this, the populations of white moths are directly affected.

The white moths are directly dependent on the tree leaves for their growth and reproduction purposes. When these tree leaves are being covered with this soot, the leaves get destroyed as this soot is comprised of carbon. So, eventually, it will lead to their loss of habitat.

Thus, the white moth population will be reduced considerably.
