What would happen if fertilization no longer occurred in a species that reproduces sexually?

a.
the species would increase in number.

b.
the species would decrease in number and eventually die off.

c.
individual variation within the species would increase.

d.
disease would destroy the species.

B - The species would decrease in number and eventually die off.

Explanation: If species no longer reproduced, new species wouldn't be created, therefor if all the species that can't reproduce died off, they would go extinct since they can no longer reproduce.
