Succession is a scientific term describing the long-term progression of biological communities that occurs in a given area [1][3][20]. Ecological succession is the gradual process in which ecosystems can change and develop over time [1]. Famed ecologist Eugene Odom once said “ecological succession is a developmental process and not just a succession of species each acting alone”[1]. Ecological succession is a process governed not by the amount of resources available to a species but the amount of competition there is for those resources [4].
Ecological succession occurs in any environment, whether it is a terrestrial or even a freshwater ecosystem [1][2]. Even though succession happens in both of these ecosystems, the phases are very different because of the distinction in the species and their community structures are two extremely different types of ecosystems[2][5].
Primary succession is the type of succession when an area has a severe disturbance and all of the original species die out as a result [2]. Throughout primary succession, an entire ecosystem can be rebuilt from scratch by exposing bare rock and because of the lack of remaining species in that ecosystem [2]. However due to this primary succession is often a slow process because of the many steps to it will take to convert bare rock to a functional ecosystem. An example of primary succession would be when lave covers the ground after a volcano erupts [2] [9].
Terrestrial succession on the other hand acts much…
