Biodiversity plays a crucial role in ecosystem resilience as it increases the overall stability and adaptability of an ecosystem. A diverse range of species ensures that there are multiple interactions and relationships within the ecosystem, creating a web of interconnectedness that helps buffer against environmental changes and disturbances. This variety also provides a greater chance for some species to adapt and thrive in the face of challenges, helping the ecosystem as a whole to recover and maintain its balance. In essence, biodiversity acts as a form of insurance for ecosystems, ensuring their ability to withstand and recover from various stressors and changes in their environment.
