In the tropics, well known pioneer forest species can be found among the genera Cecropia, Ochroma and Trema.[22]. Identify the independent variable in the experiment. The environment can be changed due to a sudden disruption or small changes overtime. 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. With the help of the community we can continue to (a) identify the oldest stage of succession shown in the figure above. Ecological succession is the process of change in the species structure of an ecological community over time. During a succession, different groups of plants grow at a site over time. . By contrast, a forest fire can typically be characterized as secondary succession because the soil remains intact and the ecosystem can typically recover much quicker because of that fact. True .
