In the next phase, frog eggs will hatch into tadpoles (tadpoles). The newly hatched tadpole still has an egg yolk reserve in the lower part of its stomach. Tadpoles that have been 1 week old will start looking for their own food in the form of algae in the water.
Tadpoles breathe using gills, until tadpoles are 4 weeks old, their legs will start to form and tadpoles will start breathing using the lungs. In this phase the tadpole begins to eat the worms and the mosquito larvae. After the 9th week, the tadpole will turn into a young frog.
