The relationship between species interactions and ecosystem stability is crucial in understanding ecological dynamics. Interactions such as predation, competition, and mutualism contribute to population control and resource allocation within ecosystems. A diverse range of species can enhance stability by providing functional redundancy; if one species declines, others can fulfill similar roles. Conversely, diminished biodiversity often results in greater vulnerability to disturbances, leading to cascading effects throughout the ecosystem. Thus, maintaining healthy species interactions is essential for ensuring resilience against environmental changes and preserving overall ecosystem health.
