Question

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

Answer 1

Answer:

• 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.
• 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

Answer 2

Answer: Here is your answer.

Explanation:

(a) Insectivorous plants are attractive so that they can attract insects and flies towards themselves. when the flies or insects sit on them the plants eat because they need nitrogen for survival and they recieve nitrogen from 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.
