Which is the best example of competition in a forest ecosystem? (a) a colony of bees builds and protects a hive together. (b) ticks live and feed on deer. (c) wolves hunt and eat rabbits. (d) blue jays and finches nest in the same oak trees.

The correct answer would be (D) Blue jays and finches nest in the same oak trees.
