Question

why do arthropods undergo moulting?​

Answer 1

Explanation:

In biology, moulting, or molting also known as sloughing, shedding, or in many invertebrates, ecdysis, is the manner in which an animal routinely casts off a part of its body (often, but not always, an outer layer or covering), either at specific times of the year, or at specific points in its life cycle.
