What is metamorphosis? Give examples.
Answer:
Metamorphosis is a biological process in which a larva transforms into an adult. It involves sudden and abrupt changes in the body structure of the animal by cell growth and differentiation. It is generally observed in amphibians (e.g., frogs) and insects (e.g., butterflies), etc.
The life cycle of a frog has three life stages.
