which scenario would most likely result in the extinction of one or more species?\nthe water temperature of a pond decreases slightly, and the members of the pond populations adapt to the change.\nthe conditions are abnormally dry for one season in a desert, resulting in the deaths of a few members of a snake population.\na predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish.\na new plant species begins growing in a forest, resulting in a new food resource for many animal populations.

Answer

Brief Explanations:

When a predatory fish is introduced into a lake, it preys on smaller fish. If the predation pressure is too high and the smaller - fish populations cannot adapt or reproduce fast enough, they may face extinction. In the first option, the pond population adapts to a slight temperature change, so no extinction is likely. In the second option, a few deaths in a snake population due to a short - term dry season in the desert do not necessarily lead to extinction. In the fourth option, the introduction of a new plant species provides a new food resource, which is beneficial rather than leading to extinction.

Answer:

A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish.
