Question

which of the following is an example of natural selection? correct answer(s) birds often dip into a pond to eat fish, casting shadows onto the water. the individual fish that are present and not eaten learn to associate shadows with birds. this results in a behavioral change where those individuals begin to swim down when shadows appear to avoid predation. a farmer takes seeds only from his biggest strawberries to plant the next season. the strawberries on his farm become larger over time. cheetahs invade a new habitat, chasing down gazelles that live there. the gazelle population becomes faster over time. climate change warms a coral reef. a population of reef fish becomes more heat tolerant over time.

Explanation:

Natural selection is survival and reproduction of organisms due to environmental pressures. In the given examples, fish - bird interaction, cheetah - gazelle interaction and fish adapting to climate - change are natural. The farmer's action is artificial selection.
