The brown tree snake is an invasive species in the island of Guam. The brown tree snake feeds mainly on birds and other animals' eggs (birds and reptiles).

Answer 1

The correct response is:

The insect population will increase drastically.

Since the brown tree snake has contributed to the decline and extinction of bird species that primarily fed on insects, the absence of these birds would result in fewer predators for the insect population, leading to an increase in insects.
