Powerpoint for science module life cycle of a frog
- 1. Life Cycle of a Frog
- 2. There are types of the life cycle of the frog • The eggs • Tadpoles • Frog lets • Frog
- 3. The Egg • Frogs lay their eggs in water or wet places. A floating clump of eggs is called frog spawn.
- 5. The Tadpole • The tadpole has a long tail, and lives in the water. It is extremely vulnerable, and must rely on its camouflage to protect it. The tadpoles also face danger by being eaten by other water animals. Sometimes the pond dries up. As a result the tadpoles die.
- 7. Frog lets • After seven weeks their hind legs begin to grow. After nine weeks, front lets grow and their tails are almost gone. After about twelve weeks the tadpoles can swim to the surface of the water and breathe in air.
- 9. The Frog • Eleven weeks after the egg was laid, a fully developed frog with lungs, legs, and no tail emerges from the water. This frog will live mostly on land, with occasional swims. The tiny frogs begin to eat insects and worms. Eventually, it will find a mate. The way this is done varies depending on the species. The female lays the eggs, the male fertilizes them, and the whole process begins again.
