Question

What is ecological succession? Distinguish between primary succession and secondary succession. 2?

Answer 1

★ Ecological succession is the process of change in the species structure of an ecological community over time. ... It is a phenomenon or 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.

★ Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.
