They can withstand and recover from disturbances better, thereby maintaining equilibrium in an ecosystem. With these traits in mind, the best option is: Climax communities have a high biodiversity. Therefore, the best description is that climax communities have high biodiversity. This trait enables them to withstand and recover from disturbances effectively.
