Biological Succession

The video tutorial explains biological succession, the process by which ecosystems change over time. It covers primary succession, which starts from bare rocks, and secondary succession, which occurs after disturbances like fires or deforestation. The video also discusses seral stages, including pioneer and climax communities, and how humans can manage succession through controlled methods.
