Answer:
Personal definition of camouflage: The ability to blend/disguise into a certain area due to its appearance in front of a similarly textured object or area. In relation to biology, it helps certain organisms survive and hide expertly from its prey when it feels in danger.
Explanation:
A good example for camouflage is the comparison of survival between a light or bright moth and a peppered moth. Peppered moth's have a white and black texture that is purposefully meant to help them camouflage from prey. In an experiment done by biologists testing this term and its correlation to natural selection, the biologists determined that a peppered moth is likely to live longer than a white moth because it is able to blend into certain environmental surfaces better than an extremely noticeable white moth.
The theory of natural selection, as I used it above, is a term used in biology conceptualized by Charles Darwin. It is also called, survival of the fittest. Meaning that specific traits of a certain species or animal in general give it the ability to survive from prey as one of its mutations facilitate its need to survive, and one of those mutations could be "camouflage", or another common example would be, the beaks of certain birds who live in certain regions of the world.
