Topic: Diversity
Total Marks: 40
Section A Answers (1 mark each)
- B – Living things show diversity by having different body features and living in different habitats. (Teaching note: Diversity means variety; same size/food is false.)
- B – Habitat is the natural home; cactus in desert, water lily in pond. (Common mistake: choosing colours which is not the cause of difference.)
- B – Fish, tree, insect are living. Rock, cloud, book, chair, sun are non-living.
- B – Birds have feathers, mammals have fur; both move, need air and water.

Section B Answers (2 marks each)
- Habitat 1: Forest – monkey. Habitat 2: Ocean – fish. (1 mark per correct pair; accept any valid e.g., desert – cactus, pond – frog.)
Marking: 1 mark each habitat+organism. - Two differences: (a) Insects have 6 legs, birds have 2 legs. (b) Insects have antennae, birds have beaks. (1 mark each; other valid: body covering, wings type.)
- Living things can grow/reproduce; non-living cannot. (2 marks for clear difference; 1 mark if partial.)

- Polar bear has thick white fur for cold snow; camel has hump and thin fur for hot desert. (2 marks: 1 for each adaptation linked to habitat.)
- Example: Frog and lily pad in pond. (1 mark organism + 1 mark habitat.)
Section C Answers (8 marks total)
- (a) Bird has feathers, fish has scales, worm has soft skin. (1 mark for stating one difference e.g., bird has feathers, fish has scales.)
(b) Different coverings suit their habitat: feathers for flight, scales for water protection, soft skin for burrowing. (1 mark reasoning.)
Image note: figure must show three animals with labelled coverings. - (a) No, false. (1 mark)
(b) Example: Water lily grows in water (not land) or mushroom not green. (1 mark with example.) - Table: Plant – cactus, feature: spiky desert plant; Animal – eagle, feature: wings. (1 mark per row correctly completed.)
- Diversity means different traits help species fit their environment. Example: Desert plants store water, rain forest plants need lots of water. (2 marks: 1 for explanation, 1 for example.)
