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

Extinction can be defined as the state or process of a species, family, or larger group that is being extinct or on the verge of becoming extinct. And extinct refers to the state of having no living members.

So, as per the definition, the 3rd option seems correct.

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

As the predator fish can finish all the smaller ones, so at one point there will be no small fish left, eventually making them extinct.
