Question

what is the relationship between disturbances and ecological stability?
disturbances generally increase stability if they are not frequent or severe.
disturbances decrease ecological stability in almost all cases.
disturbances increase ecological stability in almost all cases.
disturbances have no effect on ecological sustainability.

Explanation:

In ecology, moderate disturbances (not frequent or severe) can increase stability by promoting species diversity (e.g., small wildfires clearing space for new growth). Frequent/severe disturbances decrease stability, so the first option aligns with ecological principles. The other options are incorrect: disturbances don’t always decrease/increase stability, and they do affect ecological systems.

Answer:

A. Disturbances generally increase stability if they are not frequent or severe.
