The diagram illustrates the natural life cycle of a frog, from egg to adulthood.
Overall, the development of a frog is a cyclical and natural process that involves eleven stages, beginning with fertilized eggs and ending with a fully matured frog.
Initially, before being hatched into tadpoles, fertilized eggs grow into embryos. Subsequently, tadpoles settle under aquatic plants and develop external gills for breathing. As they grow, their tails elongate, and back limbs emerge to assist frogs in their survival and to swim in the water environment.
In the next phase, the tadpoles live off nutrients stored in their tails, and the front limbs appear. At the same time, the color of these amphibians undergoes a color transformation from dark to green. After that, the tail, which initially grows longer, gradually shortens as the hind legs and front legs appear. Finally, the young frog fully develops into an adult frog and becomes capable of living on land as well as water. Adult frogs then repeat the cycle by laying eggs.
