Final answer:
The population of moths in the habitat will change based on the conditions. If the dark form of the moth is favored and the light form is diminished due to predation, the population of dark moths will increase and the population of light moths will decrease. If conditions change again, leading to both forms having equal prevalence, the population of moths overall might increase.
Step-by-step explanation:
This question is about the population of moths in a habitat where a bird that preys on moths is introduced. Based on the given information, it can be predicted that the population of moths will undergo changes depending on the conditions:
- If the dark form of the moth is favored and the light form is diminished due to predation, then the population of dark moths will increase and the population of light moths will decrease.
- If conditions change again, leading to both forms having equal prevalence, the population of moths overall might increase.
Therefore, the expected outcome is an increase in the number of dark moths and a decrease in the number of light moths.
