Explanation:
Frogs and toads are amphibians that have the ability to live in both environments, that is why their respiratory system is highly adapted to extreme situations such as sudden climate changes, among others.
This modification of the environment many species would not tolerate because generally species always develop, live and reproduce in a single environment, such as humans, which is only in the terrestrial environment.
It is very difficult for frogs not to be able to adapt or survive climate change since they have the ability to adapt their respiratory system to two totally different media such as water and air.
