What are the four stages of complete metamorphosis?

The four stages of complete metamorphosis are indeed Egg, Larva, Pupa, and Adult. In this process, which is characteristic of insects such as butterflies, beetles, and bees, each stage has distinct characteristics and functions.

The lifecycle starts with the Egg stage, where the insect develops within a protective casing. After hatching, the insect enters the Larva stage, where it primarily focuses on feeding and growth. This stage is crucial as it prepares the insect for its transformation. Next is the Pupa stage, where the insect undergoes a significant transformation. During this time, it may appear inactive, but substantial internal changes occur, transitioning the organism into its adult form. Lastly, the Adult stage emerges, where the insect is fully formed and capable of reproduction, completing the lifecycle.

Other options include stages that do not represent complete metamorphosis or use different terminology. For example, using 'Nymph' instead of 'Larva' refers to incomplete metamorphosis, which many insects experience, but in that cycle, the creatures do not go through a pupal stage. Additionally, terms like 'Juvenile' are not utilized to describe the final adult stage in this context, as the term for the matured form is specifically
