Why do Amphibians that goes through metamorphosis?

Amphibians undergo metamorphosis as a developmental strategy that allows them to exploit different ecological niches during their life cycle. Typically, they begin life as aquatic larvae, which are adapted for living in water and feeding on plant material, while the adult form is usually terrestrial and carnivorous, allowing for a broader range of food sources. This transformation also helps reduce competition between the juvenile and adult stages, as they occupy different habitats and utilize different resources. Overall, metamorphosis enhances survival and reproductive success in changing environments.
