Levels of Biodiversity · NCERT Biology

Which level of diversity is most likely to be affected by the extinction of a single endemic species?

  1. Genetic diversity only
  2. Species diversity only
  3. Ecosystem diversity only
  4. Both genetic and species diversity
Show answer and explanation

Correct answer: Both genetic and species diversity

When a species goes extinct, it is removed from the species count (species diversity) and its unique set of genes is lost forever (genetic diversity). Both levels are therefore affected by the extinction of an endemic species.
