Question

Give reasons.
(a) Insectivorous plants are attractively coloured.
(b) Butterflies have a long tube-like proboscis.

Answer 1

a. Insectivorous plants are attractively coloured so that they can attract insects and feed upon them. Insectivorous plants grow in soil or water which are deficient in nitrogen compounds and in order to meet this deficiency, they feed on insects.

b. Butterflies have a long tube like proboscis which is a straw-like structure which enables them to drink juices and nectar. It is coiled-up like a garden hose when it is not in use.
