The transformation of the larva into an adult through drastic changes is called metamorphosis. Metamorphosis is a biological process which involves sudden and abrupt changes in the body structure of the animal by cell growth and differentiation. It is generally observed in amphibians and insects.
Examples: frogs and butterflies.

Metamorphosis is a biological process where an organism undergoes remarkable physical changes as it progresses through different life stages. Some notable examples include:
1. Frogs: Tadpoles hatch from eggs and experience metamorphosis into adult frogs. They transition from aquatic larvae with gills and tails to terrestrial adults with lungs and legs.
2. Butterflies: Butterflies undergo complete metamorphosis. They start as eggs, hatch into caterpillars (larvae), form chrysalises or pupae, and finally emerge as vibrant winged adults.
3. Beetles: Like butterflies, beetles experience complete metamorphosis. They begin as eggs, transform into grub-like larvae, progress into pupae, and eventually emerge as fully formed adult beetles.
4. Mosquitoes: Mosquitoes go through a life cycle mirroring butterflies. They start as eggs, hatch into larvae (wigglers), mature into pupae (tumblers), and eventually emerge as adult flying mosquitoes.
These examples showcase diverse metamorphic processes, displaying the incredible changes an organism undergoes from birth to adulthood in its life cycle.
