Quizplus · Accepted Answer

The process described in the question is ecological succession, which occurs when a disturbance completely eliminates a community and allows for new species to colonize and establish a new community structure over time. Rejuvenation refers to the restoration of an ecosystem to its previous state, patch dynamics involves the dispersal and colonization of species within a larger ecosystem, and symbiosis refers to the interaction between two different species for mutual benefit. Mass extinction is a phenomenon of a global level, where a majority of species on Earth become extinct in a short time span.
