Answer 2

Answer:

Exoskeleton:is the external skeleton that supports and protects an animal's body, in contrast to the endoskeleton of organism, for example, a human. In usage, some of the larger kinds of exoskeletons are known as "shells".

Endoskeleton: It's a skeleton that is on the inside of a body. The endoskeleton develops within the skin or in the deeper body tissues. The vertebrate endoskeleton is basically made up of two types of tissues (bone and cartilage).
