6. Read the article below and answer the questions.

The secret life of cockroaches

Most of us dislike cockroaches. They look ugly and may transmit bacteria that cause

diseases in humans. There are over 4000 species of cockroaches in the world but only

six of them are considered pests to our homes. Though cockroaches may be harmful to

us, they are important in nature. Cockroaches eat dead plants and help recycle plant

matter. Without cockroaches, the nutrients in the dead plants cannot return to the soil

quickly.

Cockroaches are preys of some birds and many other small animals. The following

food chain shows the feeding relationship between dead plants, cockroaches and birds.

Plant

�

Cockroach

�

Bird

(a) Cockroaches are classified as invertebrates. Why? (2 marks)

(b) Some cockroaches in the wild are active during daytime, but most cockroaches that

live in the city are active only at night. Suggest a reason for this difference.

(3 marks)

(c) Suppose you are a scientist. You have found a way to kill all cockroaches in the

world. Will you advise the governments to kill all the cockroaches in the city and in

the wild using your method? Explain briefly. (3 marks)
