Explain why geographic variation in garter snake prey choice might indicate that the behavior evolved by natural selection.

The medium-sized snake that generally lives in grassy knolls and woodlands and considered as low-level predator eating small animals is called a garter snake.Examples of garter snake prey are amphibians, small fish, insects, earthworms, tadpoles, frogs, salamanders, and leeches.

Various garter snake predators include foxes, hawks, bullfrogs, bears, and snapping turtles. Some garter snake characteristics are three-light strips, not having fangs (large sharp teeth), and background color (black, olive, or brown).

The mechanism of evolution that shapes animals' behavior by increasing their fitness for survival and reproductive success by changing and adapting to their locale is called natural selection.

The snakes and birds feeding on treefrogs is an example of natural selection. The distinct natural selection stages include variation, inheritance, time, and adaptation. The advantage that natural selection provides is the favorable trait transmission over generations.

Due to geographic variation (difference in the population of distinct areas), garter snake that resides in different geographical areas will have differences in their prey availability.

Due to natural selection, prey in abundance will increase the survival and reproductive success of garter snakes in their habitat.
