Question

select the correct answer.
human intervention has caused a decrease in many populations. what can this change lead to over time?
a. background extinction
b. increased biodiversity
c. mass extinction
d. increased genetic diversity

Explanation:

Background extinction is the normal, low rate of species loss; human-caused population decline escalates to mass extinction. Reduced population sizes lower biodiversity and genetic diversity, so only mass extinction fits as a long-term outcome of widespread human-driven population decreases.

Answer:

C. mass extinction
