Question

find the missing link/item that protects the animals. ? animal’s extenal coloration living environment camouflage mimicry imitate none of the choices

Explanation:

To solve this, we analyze the relationship between an animal's external coloration, its living environment, and a protective mechanism. Camouflage is a mechanism where an animal's coloration matches its living environment to protect it (e.g., a chameleon matching its surroundings). Mimicry involves imitating another organism, not directly related to matching color to environment. "Imitate" is a verb, not a protective item/link. So Camouflage is the correct link as it connects an animal’s coloration to its environment for protection.

Answer:

A. Camouflage
