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). The rapid increase of brown tree snakes has caused the extinction of several bird species. These birds mainly fed on insects. The brown tree snake does not have a natural predator.

Answer 1

The correct impact that the brown tree snake has on the ecosystem in Guam is:

The insect population will increase drastically.

The reasoning behind this is that with the decline in bird species (which primarily fed on insects) due to predation by the brown tree snake, there would be fewer natural controls on the insect population, leading to an increase in their numbers.
