Question

why did this pattern emerge? when you increased the number of cacti, you favored the finches with large beaks since they are able to eat the fruits atop the cacti. but when you increase the number of cacti, you also create more gathering places for tiny insects. this makes finding food a lot easier for the small - beaked finches. in this way, the introduction of the cactus favors both extreme forms of the beak - size trait. any birds that do not have these \extreme\ forms will not have easy access to the new food sources on the island. which birds are favored by the introduction of cacti and insects on the island? check all that apply. the large - beaked finches the small - beaked finches the finches with average - sized beaks none of the finches are favored by the cacti. all of the finches are equally favored.

Explanation:

The text states that large - beaked finches can eat cactus fruits and the increase in cacti provides more gathering places for insects, which benefits small - beaked finches. Finches with average - sized beaks do not have easy access to the new food sources.

Answer:

The large - beaked finches, The small - beaked finches
