Question

A) Goat

B) Llama

C) Alpaca

D) Moth

Answer 1

Hint: Fibers are thread like substances that may be natural or man-made and are used in the manufacture of other materials. These can be obtained either through plants like jute fibres or from animals like wools.

Complete Answer:

Wool is obtained from the animals like sheep, goat, yak, etc. that bear hair on their body. These wool-yielding animals have hairs on their body as it helps these animals stay warm by trapping a lot of air. This is because air is a bad conductor of heat so there is no loss of body heat.

The hair or the fleece on the skin of the sheep are of two types that form two types of fibres. One of the types is coarse beard hair and the other type is fine soft under hair close to the skin. The breeds of sheep possessing soft under hair are mostly chosen and this breed is obtained through selective breeding.

The wool from yaks is common in Tibet and Ladakh. Goats are also used for obtaining wools at certain places like mohair obtained from angora goats that are found in hilly areas like Jammu and Kashmir. The under fur obtained from the Kashmiri goat is soft and used for making Pashmina shawls.

The hair on the body of camels is also used for obtaining wool. For example, in South America, Llama and Alpaca are used for obtaining wool.

Moths or the silkworms are used for obtaining silk through the process of sericulture.

So the correct answer is D. Moth.

Note: In various parts of our country, sheep are bred for obtaining wool and the names of many breeds are kept according to the regions they are found in. These wools are used by people for knitting sweaters and shawls.
