Section A – Answers (1 mark each)

1. B
Teaching note: Diversity means differences among living things. The colour of shoes is not a biological trait of organisms; it is a human-made item detail. Correct groups are habitat, diet, body covering.

2. B
Teaching note: Mushroom (fungus), bacteria (microorganism), rose (plant) are all living. Rock, water, soil, sun are non-living.

3. C
Teaching note: Plastic bottle is made by humans from materials, not born or growing. Grass, worm, fungus are living.

4. B
Teaching note: All living things need food and water to carry out life processes. Not all have legs, not all are green, and they do grow.

5. B
Teaching note: Plants and animals both need water and air (for respiration / gas exchange). Soil and sunlight are not needed by animals in the same direct way.

6. A
Teaching note: A bird's nest is built by a bird (living) but is non-living itself. Crab, seedling, mushroom are living.

7. B
