Every animal has different life cycle. Some of life cycles are similar, but not totally the same. Frog is the one which has an interesting life cycle to be studied. Frog has 6 paces in its life cycle. The paces are eggs, tadpoles, tadpoles with hind limbs, froglet, young frog, and adult frog.
The frog eggs or frogspawns are containing thousands of eggs. These spawns usually spread through a water way. It makes them easily to be drifted and some of them fail to hatch. Frogspawns are also vulnerable. They are usually predated by some fish which are bigger. Some lucky eggs which luckily survive hatch into small and become tadpoles. Tadpole is the smallest shape of frog. It is the first after hatched from eggs. It’s typically oval and long. It also has tails and ventral fold which help it to swim. Tadpole grows up and larger as they feed on algae and bits of plant material in water. In this pace, it still breaths by gills. It is still weak, so it can be easily predated by a predator. As it begins metamorphosis, the tadpole grows hind limbs. It still eats algae –herbivorous. The limbs are growing larger time by time. After both pairs of limbs are completed, it exchanges its gills to lungs. It starts breathing with lungs, and it crawls onto land. It a little bit looks like a young frog. As it grows, it becomes a young frog. It resorbs the rest of its tail and continue grow. Its body is much larger and so are its limbs. It begins being a carnivorous. It keeps growing and reaches its adult body size. It doesn’t have tail anymore. In the last pace, it is ready to mate and produce some eggs.
Frog’s life cycle has 6 steps. This cycle gives some significant changes; a herbivorous frog becomes a carnivorous frog, breathing with gills becomes breathing with lungs, and some significant body changes. It is truly different from other life cycle.
