Question

ecosystem stability
urbanization and other human activities can cause large changes to an ecosystem that can cause the ecosystem to become unstable. all ecosystems are in a constant state of change. temperature and other environmental conditions fluctuate over time, and species can be introduced to the ecosystem. a stable ecosystem can bounce back from these normal disruptions, maintain the proportions and diversity of its species, and sustain the natural processes that cycle nutrients to support the growth and development of organisms. however, when a disruption causes a large change within a stable ecosystem, the ecosystem can destabilize, which could threaten the long - term viability of the ecosystem.
analyze old - growth forests have remained undisturbed for hundreds of years or more. from what you see in the photo above, what are some characteristics of a stable ecosystem?

Explanation:

The text mentions that a stable ecosystem can bounce back from normal disruptions, maintain species proportions and diversity, and sustain natural nutrient - cycling processes. From the photo of the old - growth forest, we can see a variety of plant life co - existing, suggesting species diversity. The forest has remained stable for many years, indicating the ability to withstand time and normal environmental changes.

Answer:

Some characteristics of a stable ecosystem include species diversity (as seen by the variety of plants in the old - growth forest) and the ability to remain relatively unchanged over long periods, withstanding normal environmental fluctuations.
