Question

which of the following best explains why an intermediate level of disturbance will greatly affect species richness in an ecosystem? ecosystems with intermediate levels of disturbance can prevent dominant species from becoming too widespread in an ecosystem. ecosystems with intermediate levels of disturbance can decrease the biomass of keystone species. ecosystems with intermediate levels of disturbance prevents invasive species from successfully migrating into the area. ecosystems with intermediate levels of disturbance resist the effects of storms, earthquakes, and volcanic eruptions

Explanation:

The intermediate - disturbance hypothesis states that moderate levels of disturbance prevent dominant species from out - competing others, thus promoting species richness. The option about preventing dominant species from becoming too widespread aligns with this concept.

Answer:

Ecosystems with intermediate levels of disturbance can prevent dominant species from becoming too widespread in an ecosystem.
