Answer:

                  Frog is a poikilotherm (cold blooded animal), i.e., it regulates its body temperatureaccording to its environment. For withstanding very cold temperatures, it undergoes winter sleep (hibernation) andsummer sleep in hot temperatures (aestivation). During this period, it lives in a dormantstage with very minimal vital body activities. Also, frog is capable of changing its body colour, though gradually, with the change in itssurrounding and climatic conditions. This capability in frog is called as comouflage and let sit escape from the predators, an essential survival parameter for living.
