Question

Why is community diversity higher in communities with moderate levels of disturbance?

Group of answer choices

-Competitively dominant species rarely exclude less competitive species after a moderate disturbance.

-Habitats are opened up for less competitive species following disturbance events.

-Less-competitive species develop higher fitness strategies versus dominant species.

-The environmental conditions become favorable.

-The resulting consistent habitat supports climax conditions, which in turn supports diversity.

Answer 1

1. Answer: Option B is correct
Explanation:
Habitats with high or low disturbance exhibit less diversity as compared to habitats with a medium level of disturbance.
At high levels of disturbance, all levels of species at the risk of going extinct.
At low levels of disturbance, dominant species can eliminate the less -adaptive species.
However, both early and late succession species can coexist at a medium level disturbance in the ecosystem.

i.e. The medium level of disturbance allows for the less competitive species to survive after a disturbance.
