Question

Why does a frog have a dual mode of breathing ?

Answer 1

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

Answer 2

This is to breathe both on land and in water.......
