A species of moth lived in a forest with a mixture of dark- and light-colored trees. The coloring of these moths is inherited. The dark moths were hidden from predators on the dark trees, and the light moths were hidden on the light trees. When the light-colored trees were killed by a disease, the forest was suddenly made up almost entirely of dark trees. Generations later, almost all the moths had the dark coloring. Which of the following gives a correct explanation?

The light moths that survived did not mate and have offspring because they thought that their offspring would easily be seen and eaten by predators.

The light moths that survived had dark offspring because the change in the environment caused the parents to decide to have offspring that would do better in the changed environment.

The light moths saw that the dark moths were less likely to be eaten by predators, so they made themselves dark as well.

The dark moths were better hidden from predators, so more of them survived. Because dark parents outnumbered light parents, there were many more dark offspring than light offspring in the next generation.

Explanation:

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
