Threats to Biodiversity · NCERT Biology

The impact of over-exploitation is most severely seen in species that have:

  1. High reproductive rates and very short generation times
  2. Short life spans and early sexual maturity
  3. Low reproductive rates and long maturation times
  4. Large population sizes with wide geographic distribution
Show answer and explanation

Correct answer: Low reproductive rates and long maturation times

Species that reproduce slowly or take a long time to reach maturity (like whales or certain large sharks) cannot replenish their numbers as fast as they are being harvested, making them highly susceptible to over-exploitation.
