Study specimens H, K, L, M and N and answer questions (a) to (f).
(a) State two observable structural differences between: (i) specimens H and L; (ii) specimens K and M.
(b)(i) State two ways each by which specimens H and M adapt the organisms to their modes of life. (ii) Name two types of food that the organism that possesses specimen H feeds on.
(c) Make a drawing, 8 cm to 10 cm long, of specimen K.
(d) Name one habitat of the organism that possesses specimen K.
(e) Name one feeding habit of each of the organisms that possesses specimen H and L.
(f) State two observable similarities between specimens: (i) H and L; (ii) K and M.
Answer Details

| M | Its streamlined body reduces resistance while moving in water. Its flippers and powerful tail aid swimming and propulsion. |
(b)(ii) The organism possessing specimen H feeds on seeds or grains and insects.
(c) Drawing of specimen K, showing a fish about 8 cm to 10 cm long.
(d) One habitat of the organism possessing specimen K is a freshwater pond.
(e)
| Specimen | Feeding habit |
|---|---|
| H | Granivorous or seed-feeding. |
| L | Insectivorous. |
(f)
(i) H and L: Both have beaks, and both possess feathers and wings.
