The life cycle of a frog is very interesting. First, a frog will lay its eggs in water. The eggs are inside a jelly-like covering. Soon tadpoles begin to grow inside the eggs. They have a head, body, and tail. Tadpoles swim in the water feeding on tiny plants called algae. As a tadpole grows, it will develop hind legs and then front legs. Then a tadpole will develop lungs and go to the surface of the water to breathe. Now the tadpole looks more like a frog. It will climb out of the water to eat insects and worms.
