Detailed explanation-1: -In arthropods, such as insects, arachnids and crustaceans, moulting is the shedding of the exoskeleton (which is often called its shell), typically to let the organism grow. This process is called ecdysis.

Detailed explanation-2: -Final answer: The periodically shedding of the exoskeleton in arthropods is called ecdysis or moulting. Q. In most of the Arthropods and especially in insects, their exoskeleton is shed off and a new exoskeleton is formed.

Detailed explanation-3: -Since the exoskeleton is hard and its outer layer is non-living, it cannot grow bigger by small increments as the human skeleton does. Instead, arthropods must go through the delicate process of shedding the old exoskeleton and expanding to a larger size before the new exoskeleton hardens.

Detailed explanation-4: -Shedding Exoskeletons: True exoskeletons cover the body of animals and provide them with the same structural support that a skeleton made of bones would. However, the exoskeleton does not grow with the organism and must periodically be shed to allow the organism to grow.

Detailed explanation-5: -Molting is the shedding of the exoskeleton (cuticle) of the previous life stage. Without molting, an insect cannot grow.
