Answer:

Organisms show a decrease in diversity only right before an extinction event.

Explanation:

Extinction is the termination of a kind of organism or of a group of kinds. This brings to an end the existence of a particular specie of organisms.

Extinctions occur only after there is a decrease in the diversity of a specie due to specific conditions such as predators, loss of habitat etc that makes the members of that specie to become endangered.
