They are adaptations to aid the animal in it's everyday life. African elephant ears are no more efficiant for hearing than Indian elephant's ears but they are much larger in external area. This is so that large blood vessels can circulate great quantities of blood through the ear flaps quickly to aid in cooling the blood and therefore the body. Aquatic animals, water-dogs, beaver etc have different ears best adapted for their environment. Other animals have ears that rotate to give them 360 degree hearing.

Do ectothemic animals control their body temperature?

Sometimes. Very small mammals will have small ears to help conserve their body heat. The exceptions to this are rabbits and hares. Also marine mammals (large and small) have lost their external ears for much the same reason. The exception to this is sea-lions who still have external ears. Large terrestial mammals have large ears as they have little need to conserve body temperature. The elephant has very large ears which they flap for the purpose of radiating away excess body heat.
