Detailed explanation-1: -Because an exoskeleton is not flexible and of a fixed size, arthropods must occasionally shed their outer layer in order to grow larger. This process is referred to as molting and is a normal part of an arthropod’s life until it reaches its full size.
Detailed explanation-2: -Answer and Explanation: The exoskeleton of an insect does not limit its growth but this is only true because an insect sheds its exoskeleton when the insect grows too large for it. The exoskeleton remains in the same shape and size it took when it first dried and hardened on the body of the insect.
Detailed explanation-3: -The problem of growth is solved in arthropods by molting, or ecdysis, the periodic shedding of the old exoskeleton. The underlying cells release enzymes that digest the base of the old exoskeleton (much of the endocuticle) and then secrete a new exoskeleton beneath the old one.
