Gills, because lungs help it live on land.
on land , frogs breathe with the help of lungs , and in water , with the help of gills.
They have lungs. Tadpoles have gills, but lose them as they grow into frogs. Frogs can still live in water as they breathe through their skin. They also can live on land via their lungs. They are amphibious for this reason
amphibians such as frogs and toads are born in water with gills and looks like a minnow; but as they grow older they get lungs and breathe oxygen
Actually Frogs only have gills when they are tadpoles.When they grow up in to Frogs the have lungs and hold their breath under water.
As tadpoles they have gills and swim in the water all day, but when they become frogs they produce lungs and lungs need oxygen. So yes they do need oxygen.
Not all amphibians do, some salamanders are live-bearers and some frogs lack a larval stage, they leave their egg as a small frog. Most amphibians do have a larval stage with gills, some will never drop the gills (neonetism) and most frogs and some salamanders will develop lungs. Most salamanders dont have lungs and breathe through their skin. There is no specified reason for having gills and lungs at different stages of their life cycle; apparently it is a good strategy. If it wasn't, frogs would be extinct ;)
Frogs begin life as tadpoles, which have gills, so they must stay in water to breathe.As they grow into frogs, they lose the gills and grow legs, the tail is absorbed, and they begin to breathe air through developing lungs.
Yes, frogs have lungs but also gills so they can breed in water.
Larval frogs or froglets have gills - just like fish. They first develop lungs and when the lungs are fully functional the gills start to dissapear. They will get smaller and will completely degenerate, just like the long tail in froglets.
No, they have gills.Sharks do not breathe with lungs, but with gills that absorb the oxygen in the water.
Yes, because when frogs are tadpoles they need to be able to breath under water so they have gills and when they turn into frogs they still have their gills but they form lungs so they can breath on land.
yes, but they can also accomplish much respiration through their skin in highly aerated water.
