The given diagram depicts the multi-stage process of producing silk.
At first glance, it is easy to realize that silk is made through a six-stage process, starting from bombyx mori moth lays 350-400 eggs on leaf and ending at the thread weaving into silk fabric.
Looking at the diagram more closely, one can see that the process begins when 350-400 eggs are laid on a leaf by bombyx mori moth, and then tiny black silkworms hatch 7-20 days later. The second step is that people provide silkworms with large quantities of mulberry leaves and they grow quickly to 3 inches (70 times original size). After 25-28 days, silkworms spin cocoons around themselves (held together by silk gum). Following that, cocoons are boiled, and then silk gum softens, so simultaneously it is easy to unwind individual silk filaments. In the closest last step, silk filaments are spun into thread and come to be very fine and strong. Eventually, the thread is weaved into fabric.
