The extinction vortex 

A. is what happens as a population decreases and becomes more vulnerable to extinction from a variety of causes. B. begins when one species in an ecosystem goes extinct and other species follow. C. is what happens when competing species fight over a single niche, often driving both species to extinction. D. is a spiral of events that occur once a species has become overcrowded through excess reproduction. E. is a spiral of events that includes introduction of competing species, overexploitation, and disease, in that order.
