Practice Writing Task 1 (Life Cycle)

The flowcharts figure the repeated-life sequences of frogs in a small pool. At first glance, there are eleven-distinct -stages illustrated, which are commenced by egg form and ended by an old frog.

As the initial. the egg is produced by an old frog before it comes to developing-processes. Egg evolves to be embryo through biological processes and then keeps developing until it becomes a tadpole that likes clinging to water-plant. After that, external gills start to appear in its body which is used to breathe while further evolution affects tail growth over time. As a result of that evolution, the tadpole completely looks like a fish.

In the succeeding stage, an adult tadpole starts to have hind legs on the back part of its body. Besides its tail grows longer, the tail also has a new function to store the food for supporting its life. As the following process, new legs emerge on the front-part of its anatomy yet its tail becomes gradually shorter. Those processes make the tadpole become a young toad then it keeps growing until it becomes an old toad as the final result. The mature-frog will produce a new egg and the process will be repeated again.
