What to Focus On

  • Biodiversity is the variety of living organisms and habitats.
  • Loss of biodiversity means a reduction in this variety.
  • Tropical regions are highly important for biodiversity.
  • Threatened, endangered, and extinct are three different categories.
  • Threatened species are at risk of losing their lives.
  • Endangered species face a high risk of extinction in the near future.
  • There are six recognised geological extinction episodes.
  • Ordovician is the earliest of the six episodes.
  • Permian extinction was especially severe.

Common Mistakes to Avoid

Threatened, endangered, and extinct mean the same thing.

Endangered species are already extinct, so no further protection is useful.

The six extinction episodes are only part of the geological history of India.
