Answer 1

Advantages: Exoskeletons provide protection against predators and environmental hazards, as well as structural support for movement and muscle attachment.

Disadvantages: Exoskeletons limit flexibility and growth potential, as they must be shed and replaced as the organism grows. This can be a time-consuming and energy-intensive process.
