Question

Differentiate between hydrosere and xerosere.

Answer 1

Hint: A plant succession arises in a freshwater area or region such as in oxbow lakes and kettle lakes. Xerosere is a plant succession that is inadequate by water availability. It consists of different stages in a xerarch succession.

Complete answer: Hydrosere is the primary succession categorization that develops in aquatic atmospheres such as lakes and ponds. Its consequences are the renovation of the water bodies and its community into a land environment. In Xerosere, bare rocks are formed when glaciers melt or in case of volcanoes erupt. Erosion of these rocks is caused by rainwater and wind loaded with soil particles.

The plants colonize in freshwaters such as the pond margin, lakes, and rivers.For example, ox-bow lakes	In this region, the plants colonize in salt marshes and sea estuaries.For example, the north shore of the Gowar.	The plants colonize on a bare rock.For example, after the melting of a glacial, newly created volcanic island.	The plants colonize on coastal dunes.For example, the south Gower

In hydroseres, the initial changes are allogenic as inorganic particles such as sand and clay are carried away from catchment areas and start filling the basin of the water body. Later, the remains of dead plants also add up these bodies and subsidize additional changes in the environment.

Note: In xerosere, the rainwater associates with atmospheric carbon dioxide that corrodes the surface of the rocks and produces crevices. Water passes in these crevices, freezes, and expands to separate boulders. These boulders move down under the influence of gravity and wear particles from the rocks.
