2. THIS IS THE DIAGRAM OF THE FROG LIFE CYCLE

3. FROG SPAWN Frogs lay so many eggs. From the three thousand eggs that one female lays, only around five will become adult frogs. The rest of the eggs or tadpoles may be eaten by birds, fish, newts, water beetles, dragonflies or simply dry up before hatching. The frogspawn that you see floating in ponds is made up of thousands of single eggs, each one having a tiny black tadpole embryo surrounded in jelly. Frogspawn will take about six to twenty one days to hatch after they have been fertilized.

4. TADPOLES consist of gills, a mouth and a tail. Immediately after hatching, they will usually stick themselves to weeds or grasses in the water. After about seven to ten days, the tadpoles will start swimming around and feeding on algae. After about six to nine weeks, the tadpoles start to absorb their tails and grow legs and arms. Now the tadpoles will eat plants and dead insects floating on the water. 

5. FROGLET By approximately twelve weeks, the tadpole has a tiny tail stub and will soon leave the water. 

6. FROG Between twelve to sixteen weeks, the froglet totally absorbs its stubby tail and leaves the water becoming an adult frog. And the cycle begins again in the spring.
