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.
Differences between genus and community
| Characters | Species in a genus | Species in a community |
|---|---|---|
| Evolutionary relationship | Different species of a genus have a common ancestory | Different species of a community have different ancestory |
| Occurence | Species in a genus generally occur in different geographical areas | Species in a community inhabit a common environment |
| Functional relationship | Species do not have any functional relation or interaction among them | Species have a direct or indirect functional relation or interaction among them |
