In the development of organisms with metamorphosis, there is a larval stage. The larva and the adult are adapted to different living conditions. What are the benefits of developing with metamorphosis?

1) development with metamorphosis eliminates competition between the adult and the larva;
2) such development increases the number of ecological niches of the species, since the habitat and food supply of the adult and larva are different;
3) in sedentary forms (for example, toothless, hydroid polyps), the larvae serve for the dispersal of the species.
