Question

Describe the birth cycle of frog.

Answer 1

There are five classes of vertebrate animals. These include fish, amphibians, reptiles, birds and mammals. The frog is an example of the amphibian class. Amphibians spend part of their life cycle in water and part on land.

The life cycle of a frog begins with a fertilized egg. The fertilized egg develops into a tadpole. The fertilized egg and tadpole stages are found in the water in the spring. The tadpole develops into an immature frog.



As the immature frog develops it is transformed via the process of metamorphosis into an adult frog. The tail is absorbed and the external gills are replaced by lungs. The adult frog lives on land and in the water and breathes air. The adult frog uses its skin for about 50% of its gas exchange, meaning that it breathes through its skin. Therefore, a frog will not stay out of water long enough for its skin to dry out. As it is said, "A dry frog is a dead frog."
