Describing a process.....!

Right...

Now we are going to describe a process.
Firstly, We have to give a introduction for the process.
In introduction, show 

1.    what does it produce...?
2.    whether it is a linear process or cyclical process
3.    whether it is a man made or natural process
4.    How many steps are ....
5.    where it starts and end.....
6.    what are the main materials ...?

Then In the body, we need to describe all the stages / steps according to the graph.

If you are interested in this.... try it.

Thank you......!
