Which of the following represents a resilience mechanism?

B)the emergence of a meadow in a recently burned forest
C)soil erosion resulting from burned soil washing away from a forest floor
D)burned trees accumulating on a forest floor after a fire

Question

Quizplus · Accepted Answer

The emergence of a meadow in a recently burned forest represents a resilience mechanism as it shows the ability of the ecosystem to recover and adapt after a disturbance such as wildfire. This meadow may have different species composition or structure than the original forest, but it has still maintained its function as part of the ecosystem.

The other options are not resilience mechanisms as they represent negative impacts of a disturbance rather than a positive response. In option A, crown fires resulting from fire suppression represent a failure of the ecosystem to adapt to the changes in fire regime. In option C, soil erosion resulting from burned soil washing away represents a loss of soil fertility, which can have long-term negative impacts on the ecosystem. In option D, burned trees accumulating on the forest floor after a fire can hinder the regeneration of the forest by blocking sunlight and creating fuel for future fires.
