Which adaptation helps an organism blend into its surroundings to avoid detection?

Camouflage is an adaptation that allows an organism to blend into its surroundings effectively, making it harder for predators or other threats to detect it. This adaptation involves the use of colors, patterns, and textures that match the environment, providing concealment. For instance, animals like chameleons can change their color to match their habitat, while others, like stick insects, take on the shape and color of twigs or leaves.

While mimicry involves one organism resembling another species for survival purposes, it does not specifically refer to blending into the environment. Warning coloration serves a different purpose by signaling to potential predators that an organism is toxic or unpalatable, thereby deterring attacks. Disguise can be a more general term and may not necessarily involve the specific visual adaptation mechanisms that camouflage entails. Therefore, camouflage is the most accurate choice for describing the adaptation that helps organisms avoid detection by blending in with their surroundings.
