Question

mass extinctions typically cause biodiversity to:
○ increase drastically
○ decrease drastically
○ stay the same
○ disappear completely

Explanation:

Mass extinctions involve the rapid loss of a large percentage of Earth's species in a short geological time frame. Biodiversity refers to the variety of life forms; when many species die off quickly, this variety drops sharply. "Disappear completely" is incorrect because some species always survive mass extinctions, and "increase drastically" or "stay the same" contradict the definition of mass extinctions.

Answer:

B. Decrease drastically
