Answer :

Final answer:

When a population's tolerance limit is reached, outcomes can include extinction, genetic isolation, and adaptation.


Explanation:

When a population reaches its tolerance limit, several potential outcomes can occur:

  • Extinction: If enough individuals fail to survive the environmental challenges, the species could become extinct.
  • Genetic Isolation: Over time, favored characteristics may lead to genetic isolation and the evolution of separate species.
  • Adaptation: Through natural selection, individuals may develop adaptations to cope with the changing environment.
