The diagram illustrates the different stages involved in the life of a frog.
Frogs emerge from embryos laid in the water and start their life as tadpoles, slowly developing into adult frogs after passing through multiple stages in the process of development.
Frogs begin their life as embryos laid in eggs in the water. The first stage of a frog's existence begins when the embryo develops into a tadpole. The second stage of development takes place when the tadpole starts developing appendages and the front legs start developing. The process of the development of the front legs is called breaking through. The next phase happens when the tadpole develops pulmonary breathing, enabling it to breathe both on land and water. It then further develops into a tadpole frog, wherein only a tail-like protrusion is present from the first phase. The frog then matures into an adult frog and the protrusion disappears.
