Answer 1

Answer: Insectivorous plants are attractively coloured.

1. Insectivorous plants generally grow in soil or water deficient in nitrogen compounds.
2. The plant body of the Drosera burmanii has a flower-like appearance. It grows close to the ground. Even its leaves are attractively pink or red with hairs at the margin.
3. Droplets of a sticky substances found on tips of the hairs attract insects.
4. These plants consume insects to fulfil their need for nitrogen. To attract the insects these plants are attractively coloured.

Answer: Butterflies have a long tube-like proboscis.
Butterflies get their nutrients by drinking the nectar from flowers. In order to reach deep into the flower to drink the nectar, butterflies have long tube-like proboscis.
