In which situation can a trait be useful in one environment but not useful in another?
Answer and explanation
Correct answer: White fur helps in snowy areas but not in green forests
The governing concept is that the value of an adaptation depends on environmental conditions. White fur can camouflage an animal against snow, reducing detection by predators and improving survival. In a green forest, the same white colour may make the animal more visible, so its advantage can disappear or become a disadvantage. Thus usefulness is relative to the environment; environments are not identical, and traits can influence survival and reproduction.
