A student is revising Animal Diversity-I: an insect larva sheds its outer skeleton before increasing in size. What should the student write in the answer sheet?

Ecdysis is the process of molting the exoskeleton. It is essential for growth in arthropods and other ecdysozoans such as nematodes. This MCQ belongs to the Arthropoda topic in Animal Diversity-I and is written to test concept understanding rather than memorized wording.
