Why is biodiversity important in ecosystems?

• A. It contributes to climate stability
• B. It attracts tourism and recreational activities
• C. It ensures the resilience of ecosystems to environmental changes
• D. It aids in urban development planning

Answer: (C)

Biodiversity is crucial in ecosystems primarily because it ensures the resilience of ecosystems to environmental changes. A diverse array of species contributes to the complex interactions and functions within an ecosystem, which can buffer the impacts of disturbances such as climate change, habitat loss, and the introduction of invasive species. When biodiversity is high, ecosystems are better able to recover from stresses and maintain their essential functions, such as nutrient cycling, pollination, and water purification. This resilience stems from the fact that different species perform various roles in an ecosystem. For example, some species may be more tolerant to extreme weather, while others may be crucial for specific processes like decomposition or seed dispersal. When disturbances occur, a diverse community can better absorb shocks because some species will thrive or adapt where others may fail. This capacity to adapt and recover is vital for sustaining ecosystem services that are essential for human survival and overall environmental health. While climate stability, tourism, and urban development may be influenced by biodiversity, they do not encapsulate the direct role that biodiversity plays in the robustness of ecological systems themselves, which is fundamental to their functioning and persistence.
