Verified step by step guidance

1. Understand the structure of arthropods: Arthropods have an exoskeleton, which is a rigid external covering that provides protection and support.
2. Recognize the limitations of the exoskeleton: Since the exoskeleton is rigid, it does not expand as the arthropod grows, which necessitates molting.
3. Define molting: Molting is the process by which arthropods shed their old exoskeleton to allow for growth and the formation of a new, larger exoskeleton.
4. Consider the biological purpose of molting: The primary reason arthropods molt is to grow larger, as the new exoskeleton allows for increased body size.
5. Evaluate other reasons for molting: While molting primarily facilitates growth, it can also help remove parasites and sometimes aid in color change for camouflage, but these are secondary benefits.
