Ecological Succession Summary

The steps of trophic levels expressed in a diagrammatic way are referred as ecological pyramids. The ecological pyramids are of three types: Pyramids of biomass, and Pyramids of energy or productivity Pyramids of energy Pyramids of Numbers: It is a graphic representation of total no.

It depicts the total dry weight of all organism at each trophic level [or total dry biomass].

Ecological succession is the same idea. It is the observed changes in an ecological community over time. It is the observed changes in an ecological community over time. These changes are fairly predictable and orderly. Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing. There are two main types of succession, primary and secondary. The stages of ecological succession are primary succession, when opportunistic species move into a mostly lifeless environment, and secondary succession, when new species displace the primary succession species once the latter has modified the environment.

To compare the functional role of the trophic levels in the ecosystem. It assumes a simple food chain. Does not accommodate food web.

An overview of ecological succession

Types of Ecological Succession: Started from a barren area thus it is uninfluenced by pre-existing community Secondary succession: Life existed earlier and follows disruption of a pre-existing community. First to colonize and it is beginning of chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem.

Common pioneer species include bacteria, fungi, and lichens species include bacteriafungi, and lichens. Aka equilibrium species, are species that will remain essentially unchanged in terms of species composition for as long as a site remains undisturbed.Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.

Secondary ecological succession is the changing sequence of communities starting with the substitution of a community by a new one in a given place. An example of this is the ecological succession of the invasion of plants and animals on an abandoned crop or land. The stages of ecological succession are primary succession, when opportunistic species move into a mostly lifeless environment, and secondary succession, when new species displace the primary succession species once the latter has modified the environment.
