Question

difference between retrogressive and progressive metamorphosis with examples​

Answer 1

Answer:

Progressive metamorphosis is when an organism increases in complexity and develops more advanced characteristics over the course of time. Retrogressive metamorphosis is the opposite in which the larval stage has complex organs but disappears or reduced in the adult stage. Examples of metamorphosis include the tadpole, an aquatic larval stage that transforms into the land-dwelling frog (class Amphibia). Starfishes and other echinoderms undergo a metamorphosis that includes a change from the bilateral symmetry of the larva to the radial symmetry of the adult.
