Explain the meaning of biotic succession taking an example of succession in a hydrosere.
Biotic Succession: The organisms interact among themselves. They not only influence their community but also change their physical or abiotic environment. The alteration in the physical environment is such as to continually favor another set of organisms till a stable community is formed. Such a biologically controlled modification in the composition of a community of a particular area is called biotic succession or ecological succession. Biotic succession is also known as a successive development of different communities in a particular area till a climax community is formed The following seven stages of the hydrosere pattern of succession can be observed: Phytoplanktonic stage (Free-floating angiosperm) Rooted submerged stage Rooted floating stage Amphibian or Reed Swamp stage Sedge meadow stage Woodland stage Forest stage.
