Answer 2

Answer:

To control the amount of light entering the eye, the iris widens or narrows to change the size of the pupil. For example, when it's dark, the iris widens and the pupil dilates, or gets bigger, to allow as much light as possible to enter the eye. The opposite occurs during the day.
