Biodiversity contributes to the health of an ecosystem primarily by providing multiple survival options for species. High biodiversity ensures a variety of species within an ecosystem, which can lead to greater resilience and stability. The presence of diverse species can enhance nutrient cycling, pollination, and pest control, as different species fulfill various roles within the ecosystem. This diversity allows ecosystems to withstand environmental changes, adapt to disturbances, and maintain their overall function and productivity.
The other options listed do not accurately reflect the role of biodiversity:
- Decreasing the complexity of food webs or limiting the number of species would generally lead to a less resilient and less healthy ecosystem.
- Ensuring that all species have only one food source would increase vulnerability and competition, potentially leading to population declines.
In summary, biodiversity is crucial for sustaining complex interactions among species and ensuring ecosystem health.
