Mimicry : In evolutionary biology, mimicry is a similarity of one species to another that protects one or both.In the case of prey species, it is a class of anti predator adaption. This similarity can be in appearance, behaviour, sound or scent. Mimics occur in the same areas as their models.For eg:- Monarch Butterfly
Camouflage : Many animals have evolved to exhibit some form of camouflage, which is an adaptation that allows animals to blend in with certain aspects of their environment. It increases an organism's chance of survival by hiding it from predators.For example Chameleon
Predation : In an ecosystem, predation is a interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked).
Adaption : An adaption, also called an adaptive trait, is a trait with a current functional role in the life of an organism that is maintained and evolved by means of natural selection.Example now Dolphins are adapted to water whereas its ancestral were said to be terrestrial.
