In an ecosystem, there are various types of bats. One type of bats, A, is
shown in photograph 1 below. When a sample of its faeces was examined,
pieces of legs and wings of a certain group of animals were found as shown
in photograph 2.
Photograph 1 (x 1/5) Photograph 2 (x 4)
(a) (i) To which group of vertebrates do bats belong? (1 mark)
(ii) Referring to photograph 1, state one external feature of bat A
through which it is classified into the group you stated in (i).
(1 mark)
(b) With reference to photograph 2, suggest the group of animals that bat
A feeds on. (1 mark)
(c) The faeces of another type of bats, B, are found to contain some seeds.

(d) A third type of bats, C, feeds on the blood of large animals. Assuming
that bats B and C have the same amount of daily food intake, compare
the daily amount of faeces they produce. Explain your answer.
(2 marks)
(e) Having different types of bats is advantageous to the survival of bats in

The following key can be used for identifying organisms under the same
phylum:
1a Absence of eyes ----------------------------------- 2
1b A pair of eyes --------------------------------------- 3
2a Six legs ---------------------------------------------- Class A
2b More than six legs ------------------------------------ Class B
3a Six legs ---------------------------------------------- Class C
3b More than six legs------------------------------------ Class D
(a) Using the above key, identify which class organism X shown in the
photograph below belongs to. (1 mark)
(b) Suggest a characteristic of the habitat of organism X. Explain your
answer. (2 marks)
(c) A newly found organism Y has a pair of eyes and fewer than six legs.
