This is an example of adaptation
Adaptation is a process by which an organism (plants or animals) becomes well suited to its environment. Adaptations are produced by natural selection and it can occur in many forms such as in organism’s means of defense and attack, in their movement, physiology, structure, reproduction and genetics. From the question, the ability of the stick insects to camouflage themselves by living among twigs in their environment in order to escape predation is an example of adaptation.
