Detailed explanation-1: -Insects have exoskeletons made of a substance called chitin.

Detailed explanation-2: -The exoskeleton of insects is composed of hard chitin, which is a polymer of acetylglucosamine and quite resistant to many chemicals. Insectivorous reptiles however have chitinolytic enzymes.

Detailed explanation-3: -The human skeleton is an endoskeleton that consists of 206 bones in the adult. It has five main functions: providing support to the body, storing minerals and lipids, producing blood cells, protecting internal organs, and allowing for movement.

Detailed explanation-4: -All insects have six legs, three body segments, antennae, and an exoskeleton.

Detailed explanation-5: -So now we know that all insects are also arthropods. Arthropods also have a hard exoskeleton, like you might see on a crab or on a beetle. They don’t have bones inside their bodies like humans. Instead, their ‘bones’ are on the outside, like a suit of armour, which is why it is called an exoskeleton.
