Primary 6 PSLE Science Quiz - Diversity (Answer Key)

Total Marks: 40
Topic: Diversity (syllabus-first, LLM-inferred; not past-year derived)

Section A Answers (1 mark each)

B – Diversity means the variety of different living things in an area.
Teaching note: "Variety" is the key word; not just count but different types.
C – Producers (e.g., plants) make their own food using sunlight (photosynthesis).
Common mistake: Confusing producers with consumers.
B – A community is many populations living together in a place.
Teaching note: Population = one species; community = many species.
B – A pond is a natural habitat supporting living things.
Teaching note: Habitat is where organisms live.
A – A population is a group of the same organisms (e.g., all ants in a garden).
Marking: 1 mark for correct example of same-species group.
C – Fungus is a decomposer that breaks down dead matter.
Teaching note: Decomposers recycle nutrients.
B – Mangrove swamps support diverse plants/animals adapted to muddy salty water.
Marking: 1 mark for mentioning variety and adaptation.
B – Temperature is a physical factor affecting survival.
Other acceptables: light, water (not asked but valid).
B – Sun → Producer → Consumer is correct energy flow.
Teaching note: Energy starts from Sun, taken by producers, then consumers.
B – Different organisms depend on one another (food webs, survival).
Marking: 1 mark for interdependence idea.

Section B Answers (2 marks each)

Sample answer: A pond has water and aquatic plants/animals, while a garden has soil and land plants/animals. [2 marks]
Marking: 1 mark for each correct contrasting feature (water vs land; different organisms).
Sample answer: A food chain shows how energy flows from one organism to another. Example: Sun → grass → grasshopper → frog. [2 marks]
Marking: 1 mark for definition of energy flow; 1 mark for three-organism example.
Sample answer: Structural: roots that breathe air above mud (e.g., mangrove tree roots). Behavioural: crab hiding in mud during low tide. [2 marks]
Marking: 1 mark each for correct type and example.
Sample answer: Decomposers break down dead organisms and return nutrients to soil/water for producers to use. [2 marks]
Marking: 1 mark for breaking down dead matter; 1 mark for nutrient recycling.
Sample answer: Negative: deforestation, pollution. Positive: reforestation. [2 marks]
Marking: 1 mark for two negatives; 1 mark for one positive.
Sample answer: A population is one species in an area; a community has many populations of different species. They are not the same. [2 marks]
Marking: 1 mark for population definition; 1 mark for community definition.

Section C Answers

[Total 2 marks]
(a) A producer is an organism that makes its own food (e.g., by photosynthesis). [1 mark]
(b) Any garden producer: hibiscus, grass, rose plant. [1 mark]
[Total 2 marks]
(a) A predator hunts and eats other animals (prey). [1 mark]
(b) Example: frog (predator) eats grasshopper (prey). [1 mark]
[Total 2 marks]
Image note: Diagram must show Grass → Grasshopper → Frog with right arrows.
(a) Grass (producer). [1 mark]
(b) Grasshopper (consumer eating producer). [1 mark]
[Total 3 marks]
(a) Water availability / light / food supply. [1 mark]
(b) If water decreases, pond organisms may move to another pond or die because they need water to survive. [2 marks: 1 for link to survival, 1 for movement response]
Marking descriptor: Must state factor change + organism response with reason.
