Question

In a food chain, assume worms → bluebirds → hawks. What would happen to the worm population if bluebirds became extinct?

a. The worm population would increase if bluebirds became extinct.
b. The worm population would decrease if bluebirds became extinct.
c. The worm population would stay the same if bluebirds became extinct.

Answer 1

The correct choice is A. Since in this food chain bluebirds are the predators of worms, if bluebirds became extinct the worm population will eventually grow since their predator is gone.
