Answers

Primary 4 Science Quiz - Diversity

Answer Key

Section A: Multiple Choice (1 mark each)

1. Answer: C (Grass)
Grass is a living thing because it grows, needs water and sunlight, and can make its own food. A rock, plastic bottle, and cloud do not show characteristics of living things.

2. Answer: C (River)
A river is non-living. It does not grow, reproduce, or need food. A butterfly, mushroom, and frog are all living things.

3. Answer: B (They can grow.)
All living things can grow. Not all living things can fly (e.g., plants), are green (e.g., animals), or live on land (e.g., fish). Growth is a universal characteristic of living things.

4. Answer: C (grow)
A seed germinating into a seedling shows that living things can grow. The seed increases in size and develops roots, stems, and leaves over time.

5. Answer: D (They do not need air.)
This statement is false. All living things need air (oxygen for most organisms) to survive. The other options are true characteristics of living things.

6. Answer: A (Ant, mushroom, fern)
All three are living things. Option B includes water (non-living), option C includes soil (non-living), and option D includes a shell (non-living, unless the animal is still inside).

7. Answer: C (respond to changes)
The plant bending towards sunlight shows that living things can respond to changes in their environment (in this case, light). This is called phototropism.

8. Answer: A (Wooden chair)
Wood comes from trees, which are living things. A wooden chair was once part of a living tree. Plastic bags, glass bottles, and metal spoons are made from non-living materials.

9. Answer: C (Rose plant)
Plants can make their own food through photosynthesis using sunlight, water, and carbon dioxide. Cats, dogs, and earthworms cannot make their own food.

10. Answer: B (All living things need air to survive.)
This is true. All living things need air (oxygen) for respiration. Option A is false (plants cannot move from place to place). Option C is false (e.g., rocks were never living). Option D is false (plants and fungi are also living things).

Section B: Fill in the Blanks (2 marks each)

11.
(a) Grass – Living
(b) Table – Non-living
(c) Bacteria – Living
(d) Cloud – Non-living

Marking: ½ mark each for correct classification (4 × ½ = 2 marks)

12. Any two of the following (1 mark each):

They can grow.
They need food and water.
They can reproduce.
They respond to changes in their surroundings.
They need air to survive.
They can move (in some way).
They produce waste.

13. Answer: Living things can grow.
The diagram shows a seed developing into a seedling and then into a young plant. This demonstrates the characteristic of growth — living things increase in size and develop over time.

14.
(a) Mushroom – Living (✓ in Living column)
(b) Pencil – Non-living (✓ in Non-living column)
(c) Goldfish – Living (✓ in Living column)
(d) Fire – Non-living (✓ in Non-living column)

Marking: ½ mark each (4 × ½ = 2 marks)

15. Answer: A car is non-living because it cannot grow, reproduce, or make its own food. Although a car can move, it does not move on its own — it needs fuel and a driver. A car does not respond to changes in its environment the way living things do, and it does not need air, water, or food to survive.

Marking: 2 marks for a clear explanation mentioning at least two characteristics of living things that a car does not have.

Section C: Structured Questions

16.
(a) A, B, and C (the plant, butterfly, and mushroom) are living things. (1 mark)
(b) They are living because they can grow, need food and water, and/or can reproduce. (1 mark)
(c) D (Rock) is a non-living thing. (1 mark)
(d) A rock is non-living because it cannot grow, reproduce, or make its own food. It does not need air, water, or food to exist. (1 mark)

17.
(a) The pictures show that living things can grow. The puppy grows into a larger adult dog over time. (1 mark)
(b) Any one of the following: They need food/water, they can reproduce, they respond to changes, they need air, they produce waste. (1 mark)
(c) Yes, the statement is correct. Living things need food to grow. Food provides energy and materials needed for the puppy's body to increase in size and develop into an adult dog. Without food, the puppy would not be able to grow. (2 marks: 1 for correct answer, 1 for explanation)

18.
(a)

Item	Living or Non-living?	Reason
Earthworm	Living	It can grow, move, and reproduce.
Soil	Non-living	It does not grow or reproduce on its own.
Grass	Living	It can grow and make its own food.
Garden hose	Non-living	It does not grow, reproduce, or need food.

Marking: 1 mark each for correct classification with a valid reason (4 × 1 = 4 marks)

(b) Grass is the living thing that can make its own food through photosynthesis. (1 mark)

19.
(a) Any three of the following: birds, ants, flowers, tree (1 mark)
(b) Any two of the following: stream, rocks (1 mark)
(c) The fallen leaf is a non-living thing. Although it was once part of a living tree, once it falls off, it can no longer carry out life processes like making food, growing, or responding to changes. It will eventually decay. (2 marks: 1 for correct classification, 1 for explanation)

20.
(a) The plant in the cupboard did not get enough sunlight. (1 mark)
(b) This experiment shows that living things need sunlight (or light) to stay healthy and make their own food. (1 mark)
(c) The plant in the cupboard would likely die if left there for another month. Without sunlight, the plant cannot make its own food through photosynthesis. It would use up all the stored food in its leaves and eventually become too weak to survive. (2 marks: 1 for prediction, 1 for reason)
