Answer Key & Explanations

Section A: Multiple Choice Questions

1. a) Adaptation – Animals adapt to maintain body temperature in different environments.
2. b) A fish having gills to breathe underwater – Gills help fish extract oxygen from water.
3. b) To store energy and survive extreme cold – Hibernation helps animals conserve energy during winter.
4. b) Hide from predators – Camouflage helps animals blend into their surroundings.
5. c) Monarch butterfly – Some animals, like birds and butterflies, migrate to warmer places during winter.

Section B: Fill in the Blanks

6. Camouflage – This allows animals to blend in with their surroundings.
7. Hibernation – Some animals hibernate to survive the winter.
8. Migration – Animals move seasonally for food, shelter, and better climate.
9. Fur or blubber – Thick fur or layers of fat help keep animals warm.
10. Speed or agility – Some animals run fast or leap to escape predators.

Section C: True or False

11. True – Some animals change their fur or skin color to adapt to seasonal changes.
12. False – Amphibians can breathe through their skin as well.
13. False – Herbivores only eat plants, while omnivores eat both plants and animals.
14. True – Penguins have blubber (fat) and dense feathers to keep them warm.
15. False – Adaptation is necessary for survival in different habitats.

Section D: Short Answer Questions

16. Animals migrate to find food, escape harsh weather, or reproduce in a better environment.
17. Camouflage helps animals hide from predators or sneak up on their prey.
18. Hibernation helps conserve energy, avoid food shortages, and survive harsh winter conditions.
19. Desert animals have adaptations like light-colored fur, water-storing bodies, and nocturnal habits to avoid heat.
20. Adaptations allow animals to thrive in different climates, landscapes, and food conditions.
