Colonisation and succession in an ecosystem

colonisation and succession in an ecosystem Mangrove swamps (colonisation & succession)  an ecosystem is a community of living organisms interacting with one another and with non-living organisms.

Primary succession is the colonisation of an area which has not supported an ecosystem before, eg sand dunes, volcanoes and new ponds secondary succession is ecological succession in an area which has supported an ecosystem whose development to a steady state has been prevented by inhibitory factors such as grazing or fire. Topics include the attributes of colonizing and early successional plants and animals, the link between colonization and speciation, the dynamics of disturbance, and mechanisms of succession ideas relating to the niche, colonizing ability, community assembly rules, and the concept of stability are all re-examined. Primary ecological succession is the changing sequence of communities starting with the first biological occupation of a place where there were no living organisms previously for example, the colonization and the following succession of communities on a bare rock is a case of primary ecological succession.

Studying the process of colonisation and succession a)explain the process of ecological colonization and succession the process in which living organisms arrive at new habitat, live, reproduce and take control of the habitat is known as colonisation. Ecological succession was formerly seen as having a stable end-stage called the climax, sometimes referred to as the 'potential vegetation' of a site, and shaped primarily by the local climate this idea has been largely abandoned by modern ecologists in favor of nonequilibrium ideas of ecosystems dynamics.

Colonisation and succession in an ecosystem

Secondary succession is one of the two types of ecological succession of plant life as opposed to the first, primary succession, secondary succession is a process started by an event (eg forest fire, harvesting, hurricane, etc) that reduces an already established ecosystem (eg a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on . Ecological succession is the observed changes in an ecological community over time the community develops in a new area that may not have been colonized previously or one that was previously . One thing that ecological succession recognizes is the death of an ecosystem that is what occurs when a climax stage ecosystem like the rain forest is destroyed by logging yet when a climax stage ecosystem is only interrupted, it is not yet understood whether it returns to the secondary stage, or would still be considered at its climax of .

  • Ecological succession is the gradual process by which ecosystems change and develop over time for example, a bare patch of ground will not stay bare it will rapidly be colonized by a variety of plants.
