Frog Life Cycle

What are the stages of the frog's life cycle?
Eggs:  Frogs lay thousands of eggs that do not have shells.  They are                 covered with a jelly-like substance that helps protect them from                being eaten by creatures in the water.  The eggs stick together                to form frog-spawn that floats to the top of the water.  A few               days later the tadpoles hatch out.
Tadpoles:  Tadpoles have a head, tail and body. They live under water                      and breathe through their gills.  They eat algae and other tiny                        water plants as they swim. After about a month, a bulge                      appears at the base of their tail where their hind legs will grow.                       They also begin to grow lungs for breathing.   Tadpoles to Froglets:  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.              Adult Frogs:  After about three months, the tadpoles have become                                 young frogs. They can live in or out of water and eat                                  insects or worms.
