PPT-Communities Within a community, species are identified based on their

role within a community niche 3 Major Niches Producers Consumers Decomposers Producers All autotrophs These convert unusable energysolar into usable chemical energy via the process of photosynthesis. A . community . is a local . assembly . of species that potentially interact.. Generally these species are on the same . trophic level. .. A community of species with similar niches is called an ecological . and . dis. -assembly. Topics for today. Assembly Rules: concepts, conflicts.

E6.1 Illustrate how community change may involve succession over time which leads to changes in the mixture of species. Resources and energy available influence productivity of a community. Basics. Community: Organisms in a specific group of interacting producers, consumers, and recyclers that share a common living space.. Population: A group of organisms of the same species that occupy a specific area. . Central question in community ecology. What processes are responsible for the identity and relative abundances of co-occurring species in local assemblages?. What is the relative importance of different ecological processes in structuring communities.

Chase and Myers (2011). variations in climatic and physiographic factors. (2) the activities of the species of the communities themselves. . These influences bring about marked changes in the dominants of the existing community, which is thus sooner or later replaced by another community at the same place. This process continues and successive communities develop one after another over the same area until the terminal final community again becomes more or less stable for a period of time. It occurs in a relatively definite sequence. This orderly change in communities is referred as succession. . The social group­ings of plant species are called plant community of which plant is the fundamental basic unit. . Characteristics of a community. . All communities have certain general characteristics which are listed below:.
