Key Topics to Revise

1

Habitats and Types of Animals

  • Habitat is the natural home of an animal.
  • Animals are grouped based on where they live: terrestrial, aquatic, amphibians, arboreal, and aerial.
  • Terrestrial animals live on land (e.g., lion, elephant).
2

Adaptations in Different Habitats

  • Desert animals like camels have humps to store fat, long legs to stay cool, and can close nostrils to keep out sand.
  • Polar animals like polar bears have thick fur and blubber to stay warm.
  • Polar bears have white fur for camouflage and furry feet to walk on ice.
3

Adaptations for Movement and Survival

  • Fish have fins and tails to swim and gills to breathe underwater.
  • Streamlined body shape helps fish move easily in water.
  • Frogs have strong back legs for jumping and swimming, and moist skin for breathing in water.
4

Adaptations Based on Food Habits

  • Animals are also grouped by what they eat: herbivores, carnivores, and omnivores.
  • Herbivores eat only plants (e.g., cow, goat) and have flat, broad teeth for chewing grass.
  • Carnivores eat flesh (e.g., lion, eagle) and have sharp teeth or beaks for tearing meat.
