Snails and beetles have exoskeletons. Hypothesize the advantages and disadvantages of having an exoskeleton rather than a backbone. Explain your answer in one or two sentences./

1 answer

Exoskeletons provide advantages such as protection against predators, support for body structure, and a reduced water loss, making them suitable for terrestrial environments; however, they can limit growth and mobility because they require molting, which leaves the organism vulnerable during the process. In contrast, having a backbone allows for greater flexibility and growth potential but may offer less protection against environmental threats.
