Through gills in the water. As they mature, they develop lungs. Then, they go on land.
with gills but when they get older their gills get covered with flaps of skin and then the lungs develop and they have to come up to the surface to breath.
They have gills.
Tadpoles are the first stage of life for frogs and toads once they hatch out of their eggs. Tadpoles are true aquatic creatures and breathe through gills, like fish. As they begin to develop into frogs they grow lungs and lose their gills until they must breathe air like other land animals.

The actual air exchange in the lungs takes place in the alveoli, which are tiny sacs at the end of the bronchioles. Oxygen from the inhaled air passes through the walls of the alveoli and into the bloodstream, while carbon dioxide moves from the blood into the alveoli to be exhaled.
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.
Gas exchange between oxygen and carbon dioxide takes place in small sacs called alveoli, which are located at the end of the respiratory bronchioles in the lungs. This is where oxygen from the air is transferred into the bloodstream and carbon dioxide is removed from the blood.
gas exchange takes place in the lungs, and at the cellular level. In the lungs, carbon dioxide and other "waste" gasses are released from the blood to be exhaled, and oxygen is absorbed into the blood. At the cellular level, oxygen is released from the blood into a cell, and carbon dioxide and other "waste" gasses are passed into the blood.
The air space keeps the stomata moist so that transpiration and gas exchange can occur. The gas exchange in the stomata needs to take place so that photosynthesis can occur. So without the air space you have no stomata, and without the stomata you have no photosynthesis which is how plants obtain their food.
worms carry out gas exchange by absorbing air through their skin
The gas exchange that takes place in the lungs are carbon dioxide and oxygen.
Capillary beds of the muscles
In the lungs.
skin is responsible for gas exchange in frogs, but not in snakes
The gas exchange that takes place in the lungs are carbon dioxide and oxygen.
Alveolar gas exchange takes place in the alveoli, which are tiny air sacs located at the ends of the bronchioles in the lungs. These structures are surrounded by a network of capillaries, allowing for the diffusion of oxygen into the blood and the removal of carbon dioxide from the blood. This exchange is facilitated by the thin walls of the alveoli and the capillaries, maximizing the surface area for gas exchange.
O2 and CO2. Their lungs aren't as developed for land life as ours so they complement that by breathing through their moist skin.
It is simpie diffusion through body surface
No
It isnt. There is no gas exchange in the trachea this takes place at the alveoli.
