The Probability of Extinction is Enhanced By

Question

The probability of extinction is enhanced by
A) Reduced population size
B) Restricted geographic range
C) Environmental change
D) All of the above

Accepted Answer

All of the options listed contribute to an increased probability of extinction. Reduced population size can lead to inbreeding and a loss of genetic diversity, making it harder for the population to adapt to changes. A restricted geographic range can make species more vulnerable to localized disasters or changes, and environmental change can directly threaten species by altering their habitats or food sources.
