Question 34
34.

A species of snakes in the Amazon Rain Forest are generally found to prefer hunting white mice. However when there is not enough food, they will hunt dark mice as well. A scientist makes the suggestion that if there are poor hunting conditions, then snakes will eat both types of colored mice because they can readily adapt their appetite. This suggestion is a
