Quizplus · Accepted Answer

An intermediate frequency of disturbance allows for a balance between species competition and survival, allowing for the coexistence of a greater number of species within the community. When there is no disturbance or a high rate of disturbance, certain species may dominate and outcompete others, leading to a lower species diversity.
