Metamorphosis in Insects and Frogs

The video provides a crash course on metamorphosis, a crucial process for species survival. It covers two types: complete metamorphosis, with four stages (egg, larvae, pupa, adult), exemplified by butterflies, and incomplete metamorphosis, with three stages (egg, nymph, adult), seen in insects like grasshoppers. Amphibians also undergo a three-stage cycle (egg, larvae, adult), as illustrated by frogs.
