Question 1

Which concept describes the ability of an ecosystem to return to its original state after a disturbance?

Accepted Answer

Resilience

Answer

Ecological resilience is the capacity of an ecosystem to recover and return to its pre-disturbance structure and function after being disturbed.

Question 2

In watershed management, a riparian buffer strip is most effective at:

Accepted Answer

Filtering agricultural runoff before it enters waterways

Answer

Riparian buffer strips of vegetation intercept agricultural runoff, filtering nutrients, sediments, and pesticides before they reach streams and rivers.

Question 3

Which of the following is an example of an abiotic factor in an ecosystem?

Accepted Answer

Soil pH level

Answer

Abiotic factors are non-living physical and chemical components of an environment; soil pH is a chemical property not produced by living organisms.

Question 4

The intermediate disturbance hypothesis predicts that species diversity is highest when:

Accepted Answer

Disturbance occurs at intermediate frequency and intensity

Answer

The intermediate disturbance hypothesis states that moderate disturbance levels prevent competitive exclusion while allowing recovery, maximizing species diversity.

Question 5

In landscape architecture, 'green infrastructure' primarily refers to:

Accepted Answer

Networks of natural and semi-natural areas providing ecosystem services

Answer

Green infrastructure encompasses interconnected networks of natural spaces and ecological systems that deliver ecosystem services like stormwater management and air purification.
