Question

what is ecological succession? illustrate the concept with the vegetatational changes in hydrosere?

Answer 1

A hydrosere is a plant succession which occurs in an area of fresh water such as inoxbow lakes and kettle lakes. In time, an area of open freshwater will naturally dry out, ultimately becoming woodland. During this change, a range of different landtypes such asswamp and marsh will succeed each other.

The succession from open water to climax woodland takes centuries or millennia. Some intermediate stages will last a shorter time than others. For example, swamp may change to marsh within a decade or less. How long it takes will depend largely on the amount ofsiltation occurring in the area of open water.
