If birds eat more green insects than brown insects what result is possible over time?
Answer and explanation
Correct answer: Number of brown insects may increase
The governing concept is natural selection acting on variation in a population. If green insects are more visible to birds, they are more likely to be eaten, while brown insects may survive and reproduce more successfully because they are better camouflaged. Across generations, the proportion of brown insects may therefore increase. Option A is correct; the other choices are too absolute or incorrectly deny selection.
