How does a diverse ecosystem respond to environmental changes?

• A. It remains unchanged and stable
• B. It becomes less productive
• C. It adapts and remains resilient
• D. It collapses rapidly

Answer: (C)

A diverse ecosystem responds to environmental changes by exhibiting adaptability and resilience. Biodiversity within an ecosystem means that there is a wide variety of species, each fulfilling different roles and functions. This variety allows ecosystems to absorb shocks and disturbances more effectively. When environmental changes occur, whether due to climate shifts, natural disasters, or human impacts, the presence of diverse species enhances the likelihood that some organisms will thrive under altered conditions.

This resilience is crucial, as it means that even if certain species are negatively affected, others may compensate, maintaining the overall functionality and stability of the ecosystem. As species interact in complex ways, diverse ecosystems can utilize different strategies for survival, ensuring that essential ecosystem services—such as pollination, nutrient recycling, and habitat provision—continue to operate effectively.

In contrast, ecosystems with low biodiversity are more vulnerable to change, as the loss of a few key species can lead to significant dysfunction and decline in ecosystem health. Thus, the ability of a diverse ecosystem to adapt to and weather environmental changes highlights its importance in maintaining ecological balance.
