Population and Biotic Community


   
 
Biotic Community
Biotic community is an association of a number of interrelated and independent populations belonging to different species, in a common environment which can survive in nature.
 
Biotic community comprises a number of populations of different species interacting between them and the abiotic environment. These populations include animal community, plant community and 'microbial community', sharing a common environment and exhibit various types of direct or indirect relationship among themselves.
 
Examples of biotic community are pond community, grassland community, forest community etc.
 
Relationship between Species in a Genus and Species in a Community
 
Both genus and community are formed of many species. But the two differ from each other in some basic characters.
 
Species in a genus have a common ancestry. They occur in different geographical regions and often have no functional relation or interaction among them.
 
Species in community do not have a common ancestry. They inhabit a common environment and have direct or indirect functional relation or interaction between them.
