What to Focus On

  • Biodiversity means variety and variability of life.
  • Three main types are genetic, species, and ecosystem diversity.
  • Walter G. Rosen coined the term in 1985.
  • Species estimates on Earth are very large and uncertain.
  • India is one of the 12 mega diverse countries.
  • India has high plant and animal diversity and many endemic species.
  • Species diversity decreases from equator to poles.
  • Tropics usually have more species than temperate regions.
  • Species-area relationship becomes linear on a log scale.

Common Mistakes to Avoid

Biodiversity means only the number of species in an area.

Genetic diversity and species diversity mean the same thing.

Ecosystem diversity is the same as species diversity because both involve many living organisms.
