Frog life cycle The presented diagram elucidates an illustration of the life cycle of a frog.

Overall, it is a natural and cyclical progress with eleven stages, commencing from fertilizing eggs and culminating with forming a mature amphibian. At the initial stage, the fertilized eggs become embryos; then these are attached to the plants in the water or pond. After that, embroys are turned into tadpoles, and its external gills for breathing appear. The next stage in the cycle, is that its tail grows bigger and bigger and stores sufficient amount of the food and nutrients from the water plant in it. Meanwhile, back hindlegs can be seen visibly. Subsequently, the creature has two front legs and can stand on its four legs, its color changes from harder to light green during this part of a frog life cycle. The smaller the tails become, the bigger the legs are. At the final phrase, this young frog alters into a mature and adult amphibian.
