3. In brief, worsted and woolen are different types of wool (long staple vs short staple), prepared in different ways, resulting in a different look and feel.

Answer:
1-fibre is a carbohydrate that cannot be eaten by us. It is found in plants we eat. Fibres are of two types - natural and synthetic fibres
4-Karnataka, Andhra pradesh, assam, jharkhand, West bengal, Tamil nadu, meghalaya, nagaland, Manipur, uttar pradesh are the states
5-we were cotton clothes in summer season
6-it is a process when an animal routinely casts of a part of the body
7-silk is manufactured from the cocoon of silk worms whereas wool is manufactured from the fur of furry animals like goat. Wool is a better insulator of heat than silk
2-fiber diameter and strength
3-the compression of a worsest draft puts more individual fibre into a length of yarn making it heavier
A woolen yarn's loosy, lofty structure traps and holds air making it warm and light.
