Answer:
Earthworm breathe through their skin. Air dissolves on the mucus of their skin, so they MUST stay moist to breathe. If worms dry out, they suffocate. As fresh air is taken in through the skin, oxygen is drawn into the worm's circulatory system, and the worm's hearts pump the oxygenated blood to the head area.
Frogs respire on land and in the water by two different methods. In water, skin acts as a respiratory organ(i.e cutaneous respiration) by diffusion. On land, lungs act as the respiratory organ. ... Air enters through the nostrils into the buccal cavity and then to the lungs
