What advantage does a biodiversity-rich ecosystem have over one with low biodiversity?

A biodiversity-rich ecosystem is generally more resilient to disturbances due to the various species inhabiting it, each playing unique roles within the ecosystem. This diversity means that if one species is affected by a disease, invasive species, or environmental changes, others can fill its role, maintaining ecological balance and functionality.

In contrast, lower biodiversity often means that the ecosystem relies heavily on a few species, making it more vulnerable to collapse if those species are threatened. Additionally, more diverse ecosystems can recover more quickly from disturbances—such as floods, droughts, or human impact—because there are multiple species that can aid in recovery processes, such as soil stabilization or regeneration.

While other options touch upon certain aspects of ecosystems, they do not accurately reflect the overarching benefits that high biodiversity provides in terms of stability and resilience in the face of environmental stresses.
