Question

Quizplus · Accepted Answer

A large-scale and rapid disturbance, such as a forest fire, can quickly alter the physical and biotic components of a natural community, leading to significant changes in the community structure. This can include changes in the relative abundance of different species, alterations to the physical environment, and disruptions to the inter-species interactions that make up the community. While other factors may also exert influence on community structure, few are as disruptive or immediate in their effects as large-scale disturbances like forest fires.
