Biodiversity is crucial in ecological systems primarily because it enhances ecosystem resilience and stability. A diverse array of species contributes to the functionality and productivity of an ecosystem. Different species often have unique roles and interactions within their habitats, such as various plants providing food and shelter, or predators maintaining the balance of prey populations.

When ecosystems are biodiverse, they are better equipped to withstand disturbances such as climate change, disease outbreaks, and habitat alteration. A rich tapestry of species can offer alternative pathways for energy flow and nutrient cycling, which reduces dependency on any single species. This diversity ensures that if one species is affected by a disturbance, others can fill its ecological role, maintaining the overall health and functionality of the ecosystem.

In contrast, ecosystems with limited biodiversity may struggle to recover from impacts, leading to declines in productivity and stability. Hence, the presence of a wide range of species is fundamental to sustaining ecological balance and promoting a resilient environment.
