Eunice is a scientist studying a grassland area in the midwestern United States. It contains many species of flora and fauna that coexist and remain relatively balanced. There have also been no recent disturbances in the area.

A stable ecosystem with many species that has experienced no recent disturbances is characteristic of a climax community. Climax communities represent a relatively balanced, mature stage of ecological succession. Primary and secondary succession describe processes of ecosystem recovery or development, not the stable community itself.
