Answer:
Sericulture, also called silk farming, is the process of making silk fibers. It starts by raising silkworms and then processing the fibers they produce.
Shearing, also known as die cutting, is a process which cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations.
Sorting is any process of arranging items systematically, and has two common, yet distinct meanings: ordering: arranging items in a sequence ordered by some criterion; categorizing: grouping items with similar properties

que 2: Ans: Sericulture, or silk farming, is the rearing of silkworms for the production of raw silk. Life cycle of a silk moth: 1. Egg →2.First stage of larvae→3.Second stage of larvae→4.final stage of larvae→ 5.Pupa →6.Adult The female silk moth lays eggs, from which hatch larvae which are called caterpillars or silkworms. They grow in size and when the caterpillar is ready to enter the next stage of its life history called pupa, it first weaves a net to hold itself. Then it swings its head from the side to side and secrets fibre made of a protein which hardens on exposure to air and becomes silk fibre. Soon the caterpillar completely covers itself by silk fibres and turns into pupa. This covering is known as cocoon. The further development of the pupa into moth continues inside the cocoon.
