Verified step by step guidance1
Understand the concept of ecological succession, which is the process by which the structure of a biological community evolves over time.
Differentiate between primary and secondary succession. Primary succession occurs in lifeless areas where there is no soil, such as after a lava flow or on a newly formed sand dune. Secondary succession occurs in areas where a disturbance has destroyed a community but left the soil intact, such as after a wildfire.
Recognize that a forested area cleared by a wildfire still has soil present, which is a key indicator that secondary succession is the type of ecological succession that will occur.
Consider the stages of secondary succession, which typically include the regrowth of grasses and shrubs, followed by the return of trees and larger plants, eventually leading to a mature forest community.
Conclude that secondary succession is the most likely type of ecological succession to occur in a forested area cleared by a wildfire, as the soil remains and can support the regrowth of plant life.
