The diagrams below show the lifecycle of the silkworm and the process for producing silk cloth.
Summarise the information in the charts and make comparisons where appropriate.

Answer

The two graphs show the lifecycle of the silkworm and the process for producing silk.

The lifecycle of the silkworm begins with a mature moth laying eggs on a mulberry leaf. After 8-10 days the eggs hatch producing silkworm larvae that feed on mulberry leaves. The feeding continues for 30-40 days after which the silkworm larvae spin a cocoon around their bodies. This process takes 4-7 days to complete. After a further 15 days the larvae hatch to form adult moths that reproduce by laying further eggs beginning a new cycle.

The cocoons created by the larva are carefully selected for the silk making process. Once selected, the cocoons are boiled in water allowing the thread of the cocoon to be unwound into thread that is usually in the range of 250-900 meters in length. The individual threads are then twisted together to form a stronger thread and then weaved into cloth in preparation for dyeing.
