What is the primary benefit of biodiversity in freshwater ecosystems?

The primary benefit of biodiversity in freshwater ecosystems is enhanced ecosystem resilience. When a freshwater ecosystem has a high level of biodiversity, it includes a variety of species that can interact in complex ways. This diversity enables the ecosystem to withstand environmental changes, such as fluctuations in temperature, water availability, and pollution levels. A more diverse ecosystem can adapt to disturbances better, as different species may respond differently to stressors, leading to a greater likelihood that some species will thrive despite challenges. This resilience is crucial for maintaining ecosystem functions, such as nutrient cycling, water purification, and habitat provision, all of which are vital for the health of the ecosystem and the services it provides to humans and wildlife alike.
