How does exoskeleton help an arthropod survive on land?

An exoskeleton provides structural support and protection for arthropods, allowing them to retain moisture and prevent desiccation when living on land. It acts as a barrier against physical damage and predators while also facilitating movement through its jointed design. Additionally, the exoskeleton helps in locomotion, enabling arthropods to navigate diverse terrestrial environments effectively. This adaptation is crucial for their survival and success in terrestrial habitats.
