Why is biodiversity crucial for ecosystems?

Biodiversity is crucial for ecosystems because it highlights the interconnections between various species and their roles within the environment. Each species contributes to ecosystem functions—such as nutrient cycling, pollination, habitat provision, and food web dynamics—supporting the overall health and resilience of the ecosystem. For example, plants produce oxygen and provide food, while herbivores help control plant populations, and predators maintain the balance of these herbivores.

This interconnectedness ensures that ecosystems can withstand environmental stressors, adapt to changes, and recover from disturbances. A diverse array of species enhances the stability and productivity of ecosystems, ensuring they can deliver essential services that benefit all life forms. In this context, biodiversity is not merely about the number of species present, but rather about the relationships and interactions that sustain ecological balance and functionality, which ultimately promotes a rich and healthy environment.
