Metamorphosis is the process through which an organism undergoes drastic changes in its form and structure during its development from larva to adult. This is commonly observed in insects like butterflies, frogs, and beetles, where the larvae transform into adults through a series of physical changes.
Asexual reproduction involves the production of offspring without the involvement of gametes.
Vivipary refers to the birth of offspring that develop inside the body of the mother.
External fertilization is the process where fertilization occurs outside the female’s body, typically in aquatic environments.
Thus, the correct term for the transformation of a larva into an adult through drastic changes is Metamorphosis.
