The diagram illustrates the life cycle of a frog, showing how it develops from eggs into a fully mature adult capable of reproduction.
Overall, the process involves seven main stages, beginning with the laying of eggs in water and concluding with the emergence of a mature adult frog that restarts the cycle.
The cycle starts when a mature female frog lays eggs on the water’s surface. These eggs contain embryos that develop over a few days before hatching into tadpoles. At this stage, tadpoles have long tails and gills, which they use to survive underwater. As they grow, their bodies enlarge, and their front legs begin to emerge, signaling the start of their transformation.
Subsequently, tadpoles lose their gills and transition to pulmonary respiration, allowing them to breathe air. Their tails gradually shorten as they develop hind legs, preparing them for life on land. In the final stage, the young frogs, now fully developed, lose their tails completely and become adult frogs capable of reproduction. The cycle then begins anew.
