The Biosphere: Change in Ecosystems

The video explores ecological succession, starting with beavers transforming forest ecosystems into ponds, illustrating ecological succession. It then explains primary succession on volcanic islands, where life begins on new land. Secondary succession is shown in forests and fields recovering from disturbances. Finally, climax communities are discussed as stable, mature ecosystems.
