Grass land Ecosystem - Community, Succession and its Process in Hydrosere

Class: 11

Community

The aggregation or assembles of living organisms having mutual relationship among themselves and to their environment is called community. Assembles of plants is called plant community and the assemblage of animals is called animal community.

Characters of community 

• Different types of species are found in the community. This is called species diversity 
• Some of the species are found to be dominant. This may be either due to number of individual of that species or due to the size of the body. Usually only one species is found dominant in a community. This is called species dominant. 
• The size of the community varies from very small to very large. The example of very small community is microorganisms found in the gut and the example of very large community is the forest community. 
• The community is changeable. One community can be replaced by another community in due coarse of time. This process is called succession. 

Succession 

Series of changes in a community in due course of time is called succession. This process is gradual and continuous. This process does not stop unless a stable community is formed. There are two types of succession.
