How does biodiversity benefit landscape ecosystems?

Biodiversity plays a crucial role in the health and stability of landscape ecosystems. One of the primary benefits of having a diverse range of species is that it enhances resilience against various threats, including pests, diseases, and changes in climate conditions. When an ecosystem is rich in diversity, it is less likely that a single pest or disease will decimate the entire population of plants or animals; instead, different species may have varying levels of resistance to these threats. This genetic and species diversity ensures that some organisms can thrive even when others are challenged, contributing to the overall stability and health of the ecosystem.

Furthermore, a diverse landscape can better withstand climate impacts, such as changes in temperature and precipitation. Different species may respond differently to climate stressors, which can buffer the ecosystem against sudden changes. This adaptability is essential for maintaining the balance and function of the landscape as a whole.

The other options do not fully capture the positive aspects of biodiversity. While competition for resources can occur in a diverse ecosystem, this competition can actually lead to a more balanced and healthier environment rather than being a strictly negative effect. Reducing the need for soil amendments isn't a direct benefit of biodiversity, though it can be an outcome of a well-balanced ecosystem. Lastly, biodiversity typically enhances the
