What role does biodiversity play in maintaining ecological balance?

• A. It eliminates invasive species
• B. It enhances adaptability to changes
• C. It simplifies food webs
• D. It decreases the number of species

Answer: (B)

Biodiversity plays a crucial role in enhancing adaptability to changes within ecosystems. A diverse range of species contributes to the resilience of an ecosystem by ensuring that there are various functional roles within it. For instance, different species may respond differently to environmental changes, such as climate fluctuations or disturbances. This variety increases the likelihood that some species will thrive even when conditions shift, thus helping to maintain the overall health and stability of the ecosystem.

Moreover, higher biodiversity can facilitate processes such as nutrient cycling, pollination, and pest control, which further supports the adaptability of the ecosystem. A rich variety of species can lead to more robust interactions and relationships, allowing the ecosystem to better absorb and recover from changes. This adaptability is essential for ecological balance, as it ensures that systems can withstand stressors and continue to function effectively in providing essential ecological services.
