Detailed explanation-1: -T F Some damaged ecosystems can recover after a disturbance. Ecosystems only change slowly after natural disturbances. Changes in ecosystems proceed in a fairly predictable way after a disturbance occurs.

Detailed explanation-2: -Ecological succession is a series of more-or-less predictable changes that occur in a community over time. Ecosystems change over time, especially after disturbances, as some species die out and new species move in. Over the course of succession, the number of different species present typically increases.

Detailed explanation-3: -The change a terrestrial ecosystem experiences as it recovers from a disturbance depends on the intensity and magnitude of the disturbance. The major mechanisms of recovery in such ecosystems are primary and secondary succession. Primary succession occurs in a landscape that previously was devoid of life.

Detailed explanation-4: -Ecological succession is the process of change in the species structure of an ecological community over time. It is a process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat.
