About Clements' distinction between primary succession and secondary succession, Cowles wrote (1911): This classification seems not to be of fundamental value, since it separates such closely related phenomena as those of erosion and deposition, and it places together such unlike things as human agencies and the subsidence of land.

Plant succession may be of two kinds: (i) Primary succession: Debates continue as to the general predictability of successional dynamics and the relative importance of equilibrial vs. non-equilibrial processes. 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. Possums are hosts for young ticks and eat many of the young ticks before they can feed. Small plants such as grasses and some ferns use this soil and grow.

Plants that colonise bare ground are typically hardy and low-growing. Refer to the figure or diagram to answer the question. [12], The trajectory of successional change can be influenced by site conditions, by the character of the events initiating succession (perturbations), by the interactions of the species present, and by more stochastic factors such as availability of colonists or seeds or weather conditions at the time of disturbance.
