Which of the following provides the most accurate example of primary succession? [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. Need a quick refresher of the unit as a whole? Primary succession is characterized by plants establishing themselves in areas that were initially devoid of soil (usually bedrock).
