Which of the following is a characteristic of a stable ecosystem?

A stable ecosystem is characterized by high species diversity because diverse ecosystems tend to be more resilient to changes and disturbances. This resilience arises from the interactions among different species, which help to maintain balance and functionality within the ecosystem. High species diversity contributes to various ecological processes, such as nutrient cycling, pollination, and food web stability, making the system stronger against environmental pressures such as climate change, disease, and habitat destruction.

In contrast, frequent disturbances can disrupt the ecological balance and negatively impact the stability of an ecosystem. Rapid changes in species composition can signify an ecosystem that is not stable, as it may indicate that species are unable to adapt to environmental pressures or that the ecosystem is undergoing a transition. Limited nutrient availability can lead to low productivity and diminish the ability for diverse species to thrive, potentially resulting in a less stable and more vulnerable ecosystem. Thus, high species diversity is crucial for promoting the health and longevity of ecosystems.
