The significance of predator-prey relationships in ecosystems lies in their role in maintaining ecological balance and promoting biodiversity. These interactions regulate populations of species, preventing overpopulation and resource depletion. Predators help control the abundance of prey species, which can influence vegetation patterns and overall ecosystem health. Additionally, such relationships foster natural selection and evolutionary adaptations among species. Healthy predator-prey dynamics contribute to ecosystem stability and resilience, enabling environments to withstand disturbances and changes over time.
