The diagrams below show the life cycle of the silkworm and the stages in the production of silk cloth.

Sample Answer:
The first diagram illustrates the different stages in life cycle of a silk worm while the second diagram depicts the process to produce silk cloth.

Overall, there are four major stages in life cycle of silk worm. In addition, production of silk cloth commences with selecting a cocoon and ends with weaving the threads.

The life cycle of silkworm begins when eggs are laid on the mulberry leaves by adult moths. In a period of 10 days, the eggs hatch into silkworm larva. The larva feeds on the mulberry leaves and in a period between four to six weeks, they start producing silk thread, which encases their body. The process continues for about 3 to 8 days until it matures to a cocoon. Finally, after 16 days the cocoon evolves to a moth which has the ability to fly, and the cycle continues.

For the silk cloth production, firstly cocoons of good quality are selected and boiled inside a container to unwind the silk threads. Each thread is about 300 to 900 meters long. After that, the threads are twisted and put in a container filled with dye. Finally, the threads are woven and dyed once more to produce silk cloth.
