Animals go through life cycles just like plants do:
birth, growth, reproduction, death, and all over again.
Let's look at the life cycle of a frog. A frog
begins as an egg. Frog eggs float on the water. They look like
clumps of jelly. Each little egg has a dark speck inside of
it. The speck grows bigger and bigger. It begins to take
shape. When it hatches it is a baby frog called a tadpole.
A tadpole has a broad face and a long flat tail. It can now swim.
As the tadpole grows it develops two legs at the back of
its body. Soon, two more legs grow in the front. At about the
same time, the tadpole's tail begins to shrink. It now looks more
and more like a frog.
The new frog grows until it is ready to reproduce.
Remember, reproduce means make more of its own kind. A female frog
lays about one thousand eggs at a time. A male fertilizes them,
and the fertilized eggs float in the water. These eggs look like
clumps of jelly with dark specks in them. The specks get bigger and
bigger. The life cycle of a frog goes on and on.
