What is the definition of metamorphosis in insects?

The definition of metamorphosis in insects refers to the series of changes they undergo from egg to adult. This process typically includes distinct life stages such as egg, larva (or nymph), pupa, and finally adult. Each of these stages is characterized by specific physical and developmental transitions, allowing the insect to adapt and thrive in its environment throughout its life cycle.

Understanding this process is crucial for recognizing the biology of insects, as well as their roles in ecosystems, including their reproductive strategies and survival mechanisms. The option that describes metamorphosis as the progression from egg to adult captures the full scope of this transformative process, highlighting the complexity of the life cycle that many insects experience.
