Question

which of the following is a measure of how likely an ecosystem is to return to its original biodiversity and productivity after a disturbance?
diversity
intensity
resistance
resilience
which statement predicts the impacts of a disturbance with a longer duration?
the disturbance will affect a smaller spatial coverage with greater effects on the energy transfer of the ecosystem.
the disturbance will affect a larger spatial coverage with greater effects on the energy transfer of the ecosystem.
the disturbance will affect a smaller spatial coverage with reduced effects on the energy transfer of the ecosystem.
the disturbance will affect a larger spatial coverage with reduced effects on the energy transfer of the ecosystem.

Explanation:

1. Resilience is the measure of an ecosystem's ability to return to its original biodiversity and productivity after a disturbance. Diversity refers to the variety of species, intensity is the strength of the disturbance, and resistance is the ability to withstand a disturbance without change.
2. A longer - duration disturbance is likely to affect a larger spatial coverage and have greater effects on the energy transfer of the ecosystem. For example, a long - lasting drought can spread over a large area and disrupt the food web and energy flow in an ecosystem.

Answer:

1. D. resilience
2. B. The disturbance will affect a larger spatial coverage with greater effects on the energy transfer of the ecosystem.
