What to Focus On

  • Biodiversity is the variety of living organisms.
  • Classification is a systematic way of organizing life forms.
  • Biodiversity supports food chains, oxygen production, nutrient cycling, and ecosystem stability.

  • Endemic species are found only in a particular region.
  • Biodiversity hotspots have many endemic species and high habitat loss.
  • The Western Ghats, Indo-Burma, the Himalayas, and Sundaland are biodiversity hotspots.

  • Aristotle used habitat and external appearance for grouping animals.
  • The two kingdom system divided life into Plantae and Animalia.
  • Protista, Monera, and Fungi were added to solve classification problems.

Common Mistakes to Avoid

Living organisms can be classified correctly by one visible feature, such as size, colour, or movement.

Amoeba and Paramecium should be placed with animals because they move like animals.

Bacteria and cyanobacteria belong to Plantae because they can make food.
