Answer 2

Wool

Wool is the most commonly used animal fibre. Wool is the soft, wavy (or curly) hair which covers the body of a sheep. Wool is a modified form of hair that grows with a waviness. Because of the waviness of wool, the woollen fabrics have a greater bulk (than cotton fabrics) and hence trap more air. Due to this, woollen fabrics keep us more warm during cold, winter days.

Wool is obtained from the fleece (or hair) of sheep. Sheep grow wool on their body and once a year, this wool is sheared (cut off). Though wool comes mainly from sheep, some other animals also give us wool.

Animals That Yield Wool

Wool comes from the animals like sheep, goat, yak, camel, Liama and alpaca.

The wool yielding animals have a thick coat of hair on their body to keep them warm during cold winter season. The hair (or wool) trap a lot of air. Air is a poor conductor of heat. So, the air trapped in hair (or wool) of these animals prevents their body heat from being lost to cold surroundings and keeps them warm in winter.

The hair (or wool) of these animals is removed only once in a year at the beginning of summer season. They can survive in hot weather without hair. And by the time winter comes, the thick hair(or wool) grows again on the body of these animals.
