How is frog adapted to amphibians habitat?
Answer: In order to live on land, amphibians replaced gills with another respiratory organ, the lungs because frogs are amphibians, they have adaptations that help them to live on land and in water. They are cold blooded, which means that their body temperature change with that of the environment.

On the surface of the ground or in water they move by undulating their body from side to side. In frogs, the hind legs are larger than the fore legs, especially so in those species that principally move by jumping or swimming.
In what ways amphibians and reptiles have adapted to live on land?
Laying eggs that can survive on land is a major adaptation allowing reptiles to live away from aquatic environments. Amphibians tend to lay soft, gelatinous eggs, and most use forms of external fertilization. Such eggs wouldn’t survive the dry conditions found on land.
What makes the amphibians survive both in land and water?
Amphibians are vertebrates (animals with backbones) which are able, when adult, to live both in water and on land. Unlike fish, they can breathe atmospheric oxygen through lungs, and they differ from reptiles in that they have soft, moist, usually scale-less skin, and have to breed in water.

Why do amphibians lay eggs in water?
Amphibian Eggs
Unlike other tetrapod vertebrates (reptiles, birds, and mammals), amphibians do not produce amniotic eggs. Therefore, they must lay their eggs in water so they won’t dry out. Their eggs are usually covered in a jelly-like substance, like the frog eggs shown in Figure below.
Is a turtle a reptile?
Reptiles are turtles, snakes, lizards, alligators and crocodiles. Unlike amphibians, reptiles breathe only through their lungs and have dry, scaly skin that prevents them from drying out. Amphibians and reptiles are together called herpetofauna, or “herps” for short.
Do amphibians lay eggs?
Amphibians reproduce by laying eggs that do not have a soft skin, not a hard shell. Most females lay eggs in the water and the babies, called larvae or tadpoles, live in the water, using gills to breathe and finding food as fish do. As the tadpoles grow, they develop legs and lungs that allow them to live on land.
Can amphibians breathe underwater?
Amphibians breathe under the water through their gills and their skin. When in a larval stage, all aquatic and terrestrial amphibians breathe underwater, for example, frogs, toads, and salamanders.
What are behavioral adaptations of a frog?
Some frogs have behaviour adaptations to conserve water, including becoming nocturnal and resting in a water-conserving position. Some frogs may also rest in large groups with each frog pressed against its neighbours. This reduces the amount of skin exposed to the air or a dry surface, and thus reduces water loss.
What adaptations help a frog to live on land as well as in water?
Below are some adaptations required for frogs to live both on land and in water. 1) They are poikilotherms or cold blooded meaning that their body temperatures change with that of the environment. 2) A frog has both lungs as well as skin for breathing. 3) They have the presence of webbed feet, which help them to swim.
