Question

The ability of the frog to change colour is called
A. Mimicry
B. Metachrosis
C. Camouflage
D. All of the above.

Answer 1

Hint: The mimicry is a phenomenon that is found in some specific organisms in which they resemble other organisms of other taxon is called the mimicry. Mimicry can be classified into Mullerian mimicry and Bayesian mimicry, and self mimicry. Mimicry can be found in many organisms like insects, reptiles, mammals, etc.

Complete answer:
The changing of color of a frog is known as mimicry. It is found that the changing color of the frog can be the effect of physiological stress or predatory action. The characteristics of the frog that involves the change of color according to the need are named mimicry. Example: Ranitomeya is a poisonous frog that shows Mullerian mimicry.
The ability of some organisms which involves the changing of color voluntarily is Known as metachrosis. It is mainly found in reptiles like chameleons and fishes.
The process which involves an organism to hide from the environment by using various physiological combinations like illumination or coloration is called camouflage. Chameleon camouflage by changing color like green to hide within the leaves for better predation.

So, the correct answer is option A. Mimicry.

Note: The organism which possesses the feature called mimicry is known as a mimic and the organism which is mimicked by the mimic is called a model. Mimicry has been done by some animals for various reasons which include predation ( predators mimics a non predatory animal just to confuse the prey), protection (some prey mimics for survival), breeding (many male frogs change their color to attract the female), etc.
