Question
Which of the following is a structural adaptation:
- The bright-colored wings of a butterfly warn predators that it is poisonous.
- A hognose snake that rolls over slows down its breathing and hangs its tongue out to play dead to its predators.
- A herd of buffalo encircling their younger ones to protect them from a pack of wolves.
- A dung beetle rolling a piece of dung across the desert.
Hint:
ADAPTATION is any structure or behavior that helps an organism survive in its environment. A STRUCTURAL ADAPTATION is an inherited body structure.
The correct answer is: The bright-colored wings of a butterfly warn predators that it is poisonous.
An adaptation can be structural, meaning it is a physical part of the organism. One of the butterfly's adaptations for predator avoidance is to have the same color or pattern as its surroundings, making it difficult to see. When the wings of the question mark butterfly (Polygonia interrogationis) are open, its bright orange color makes it highly visible.
