What does the term 'molting' refer to in arthropods?

The process of attacking other insects
The process of shedding an outgrown exoskeleton
The process of laying eggs
The process of building nests

The correct answer is: The process of shedding an outgrown exoskeleton

The term 'molting' in arthropods specifically refers to the process of shedding an outgrown exoskeleton. As arthropods grow, their rigid exoskeleton does not expand. To accommodate their increasing size, they undergo molting, during which they break away from the old exoskeleton and form a new, larger one. This process allows for growth and is essential for the life cycle of arthropods, including insects, crustaceans, and spiders. During molting, the arthropod is often vulnerable until the new exoskeleton hardens and provides adequate protection. This biological process is critical as it not only facilitates growth but also enables the arthropod to refine its body structure and repair any damage. Therefore, it is a fundamental aspect of their development and survival.
