Total Marks: 40
Topic: Diversity

Section A Answers (1 mark each)

B) A mango tree
Teaching note: A mango tree is alive — it grows, needs water, and can make its own food. Wooden chair, plastic cup, and stone are non-living.
C) A cloud
Teaching note: A cloud is water droplets in the sky, not alive. Cat, rose, and worm are living.
C) fungus
Teaching note: Mushroom is a fungus, not a plant or animal. Fungi break down dead matter.
