Explain how an extinction vortex can lead to the extinction of a small population. describe how a greater prairie chicken population was rescued from an extinction vortex.

Extinction vortex occurs when demographic, environmental, and genetic stochasticity interact with each other and with deterministic factors, such as habitat quality, to reinforce the demise of a small population. The small population becomes completely unable to recover especially due to lack of genetic variability.

The numbers of-of the prairie chicken population could not be reversed through the management of habitat alone but  by a transfusion of genetic variation in the population. This was done to help the species achieve minimal viable population size at which a species is able to sustain its numbers.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
