To predict what will happen to the moth population in this area, we need to consider the concept of natural selection and how it operates in the context of the moths' habitat.
The image shows two moths of the same species but with different colors. This suggests that there is genetic variation within the moth population, leading to the presence of both dark and light colored moths.
If the habitat of the moths does not change, we can apply the principle of natural selection to understand what might happen. Natural selection favors individuals with traits that enable them to better survive and reproduce in their specific environment. In this case, the habitat consists of the bark of trees.
Option A states that there will be no change in the moth population if the habitat does not change. However, this answer ignores the concept of natural selection and does not account for any potential advantages or disadvantages associated with the moths' coloration.
Option B suggests that the lighter moth population will have a better chance of survival due to camouflage, leading to an increase in light moths and a decrease in dark moths. This answer takes into account the role of camouflage in the moth's environment. Light moths may be better able to blend in with the bark of the trees, making them less visible to predators. Dark moths, on the other hand, may stand out more and be more vulnerable to predation.
Option C suggests a population shift to favor the light moth. It states that the light moth population will increase because the dark moths will leave the area. This answer assumes that the dark moths will leave the area for some reason, potentially due to predation or reduced reproductive success.
Option D states that there will be no significant change in the moth populations, light or dark, as the seasons change and both moths will be hidden by foliage growing on the trees. This answer considers the potential impact of foliage on the visibility of the moths, suggesting that both moth colors may be equally hidden during certain seasons.
Based on these options, we can infer that the most likely answer is B - the lighter moth population will have a better chance of survival due to camouflage, leading to an increase in light moths and a decrease in dark moths. However, it is important to note that without additional information about the specific characteristics of the moths and their habitat, we cannot make an entirely definitive prediction. Factors such as predators, prey availability, and other environmental conditions could also influence the moth population.
