Biologists hypothesize that the bright coloration of certain tropical frogs serves as a warning to predators that the frogs are toxic, a phenomenon known as aposematism.
Which observation, if true, would most strongly support the biologists' hypothesis?
- A
Tropical environments contain many brightly colored organisms.
- B
Some brightly colored frogs are active during the day.
- Ccheck_circle
Predators that consumed brightly colored frogs once subsequently avoided all frogs with similar coloration, while continuing to eat dull-colored frogs.
- D
Frogs with bright coloration tend to be small.
Explanation
A demonstrates the predicted learned-avoidance behavior tied specifically to bright coloration, supporting aposematism. B, C, and D are tangential.
