Why do tadpoles have gills to breathe?

Tadpoles have tiny external gill flaps that extract oxygen from water as it passes over them. Tadpoles open their mouths as they swim and take in water. As the mouth closes, muscles transfer the water to the gills. As tadpoles mature the gills are absorbed by the body as other respiratory systems develop.

What do frogs have that allow them to breathe out of the water?

When the frog is out of the water, mucus glands in the skin keep the frog moist, which helps absorb dissolved oxygen from the air. A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs.
