on land , frogs breathe with the help of lungs , and in water , with the help of gills.
Yes they do. All frogs, salamanders and Caecillians have lungs. However the tadpoles do not and develop lungs in the time that they live in water.
Gills, because lungs help it live on land.

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.
backward movement of epiglotis
The epiglottis is the flap that prevents food and water from entering the trachea.
frogs breathe through there skins. but the frog has lungs but no ribs! They don't. Frogs can hold their breath for a very long time but they still have to come to the surface to breath air.They don't, they hold their breath like we do, they can just do it a long time. During their tadpole stage, they breathe under water through their skin, using internal gills. When they mature into frogs, they develop lungs and then can only breathe air using their lungs.
Amphibians such as toads, frogs and newts, etc.
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
Frogs can breathe through their skin, which allows them to breathe underwater for long periods of time. They also have lungs, allowing them to perform strenuous activities in water.
