Question

Choose the correct order of the steps with respect to silkworm rearing.

I. Eggs are incubated under controlled conditions

II. Silk cocoons are boiled

III. Silk fibres are extracted

IV. Egg hatch into larvae

V. Larvae weave a cocoon around themselves

VI. Larvae feed on mulberry leaves

• A. I, II, III, IV, V, VI
• B. I, IV, VI, V, III, II
• C. I, IV, V, VI, II, III
• D. I, IV, VI, V, II, III

Answer 1

The correct option is D

I, IV, VI, V, II, III

Silk is obtained from the cocoon of the silkworm. These are the steps followed for farming silkworms and extraction of silk.
i. The eggs of the silkmoths are carefully cultured under controlled conditions.
ii. Larvae or silkworms hatch from eggs
iii. The larvae feed on mulberry leaves
iv. Once the larvae have grown, they spin a cocoon of silk in order to metamorphose into an adult silk moth.
v. These cocoons are collected for the silk. The larvae are boiled and only the silk cocoons are used to collect the silk thread.
vi. Then the silk fibre is obtained from these cocoons.

So the correct order of the process would be I, IV, VI, V, II, III.
