The choroid and the auricle are similar because,
one collects light and the other collects sound?

You might say that, but the choria does no really "collect" light; it provides a way for the retina to receive blood for nourishment. The retina does the "collecting" of light. The auricle (or "pinna") collects and funnels sound into the ear.
yes one collects light and the other collects sound, if your doing it from a Penn Foster class
