Answer:
Stage 1: Egg
Stage 2: Tadpole (Larva)
Stage 3: Adult
Explanation:
1. Many species lay their eggs in calm water among vegetation, where the eggs can develop in relative safety. The female frog lays numerous eggs in masses that tend to clump together in groupings known as spawn. As she deposits the eggs, the male releases sperm onto the eggs and fertilizes them.
2. Tadpoles, frogs' larvae, have rudimentary gills, a mouth, and a long tail. For the first week or two after the tadpole hatches, it moves very little. During this time, the tadpole absorbs the remaining yolk left over from the egg, which provides much-needed nourishment. After absorbing the yolk, the tadpole is strong enough to swim on its own.
3. At approximately 12 weeks of age, the tadpole's gills and tail have been fully absorbed into the body, meaning that the frog has reached the adult stage of its life cycle. It is now ready to venture out onto dry land and, in time, repeat the life cycle.
