Unwanted dumping of chemicals has caused pollution in a particular region, leading to a decrease in the number of insects. bluebirds feed on these insects, and bigger birds prey on the bluebirds. what effect would this situation likely have on the population of the bluebirds and their predators?

Population size of both bluebirds and their predators would reduce due to unavailability or less availability of food.

Explanation:

Reduced population size of prey leads to food unavailability for their predators. Hence, decreased prey population results in reduced population size of prey. Here, insects are prey for blue birds. So, reduced population of insects would starve the bluebirds. Similarly, the reduced population size of bluebirds would adversely affect their predators.
