Which term describes the external skeleton of insects?

Explanation:
An insect’s external skeleton is called an exoskeleton. It’s a tough outer covering, mainly of chitin, that protects the body, helps prevent water loss, and provides a surface for muscle attachment. Growth requires molting, where the old exoskeleton is shed and a larger one forms. An endoskeleton is internal, as in vertebrates; a carapace is a shield on some crustaceans and arachnids, not a general term for insects; outer skeletons isn’t a standard term.
