Which piece of observation would support your explanation that the chameleon use a physical characteristic adaptation to survive in its environment?

The chameleon is able to change its color to blend with the surrounding environment.

Explanation:

The chameleon is able to utilize the camouflage adaptation to remain hidden against the predators and can also catch the prey. They are able to change their color from brown to green on grass and vice versa for tree trunk so that on blending with the color of the external environment chameleons remain undetected this is a kind of phenotypic advantage over other reptiles that help them to remain undetected by predators like birds, snakes, and others and help in their survival. This is a kind of natural selection.
