7.1 Succession Ecological succession is the directional change in the composition of species that occupy a given area through time: it involves initial colonization and establishment of pioneer plant species, followed by their replacement with other species until a relatively stable community is formed. Ecosystems are made up of all the interacting biotic (food availability, competition and predation)and abiotic (non-biological environment ? pH, temperature, rainfall and humidity)factors in a particular area within which there are a number of communities of organisms. Ecosystems constantly change, Succession is the term used to describe these changes, over time, in the species that occupy a particular area. A sere (seral stage) is the series of stages in succession.
