A new predator is introduced into the ecosystem shown in the food web below. This predator feeds on bees and mice. How will this most likely affect the species in this ecosystem?

There will be a decrease in bees and mice which will cause an increase the black bear population and a decrease in the fox population.
There will be an increase in bees and mice which will cause an increase in the populations of both black bears and foxes.
There will be an increase in bees and mice which will cause a decrease in the black bear population and an increase in the fox population.
There will be a decrease in bees and mice which will cause a decrease in the populations of both black bears and foxes.

There will be a decrease in bees and mice which will cause a decrease in the populations of both black bears and foxes.

The most likely answer is: There will be a decrease in bees and mice which will cause a decrease in the populations of both black bears and foxes.

The introduction of a new predator that feeds on bees and mice will lead to a decrease in the populations of these two prey species. This decrease will have a cascading effect on the populations of predators higher up in the food chain, such as black bears and foxes, as they will have less prey available to them. Therefore, the populations of both black bears and foxes are likely to decrease as a result of the introduction of the new predator.
