For a population of grasshoppers, the largest individuals are removed by birds. the smallest individuals starve to death. over time individuals in the population become more similar. this is an example of selection.

The correct answer is "stabilizing".

Explanation:

Stabilizing selection is a type of natural selection at which the individuals of a population are selected towards the mean values of a trait. In this example, the large grasshoppers are removed by birds and the small ones starve to death. Therefore, the medium grasshoppers are the ones selected by nature, which stabilizes the size trait of the grasshoppers population. This is an example of stabilizing selection and, since most organisms are very similar among themselves, is the most common type of natural selection.
