Question 1

Which of the following best describes a 'trophic cascade' in an aquatic ecosystem?

Accepted Answer

The indirect effects of apex predator removal on lower trophic levels and vegetation

Answer

A trophic cascade occurs when changes at the top predator level ripple down through prey and plant communities, altering overall ecosystem structure.

Question 2

The Envision credit NW1.1 'Preserve Prime Habitat' is most focused on:

Accepted Answer

Minimizing land disturbance during construction to protect high-quality ecological areas

Answer

NW1.1 targets avoiding or minimizing disturbance to high-quality habitats, particularly those with rare species or ecological significance.

Question 3

In landscape ecology, habitat 'connectivity' is important primarily because it:

Accepted Answer

Allows species to move between patches, supporting gene flow and recolonization

Answer

Connectivity enables wildlife movement among fragmented habitat patches, sustaining genetic diversity and allowing recolonization after local extinction events.

Question 4

Which water quality parameter is most directly linked to eutrophication in freshwater systems receiving agricultural runoff?

Accepted Answer

Total phosphorus concentration

Answer

Excess phosphorus from fertilizer runoff is typically the limiting nutrient that triggers algal blooms and subsequent eutrophication in freshwater lakes and ponds.

Question 5

The Envision framework credits that address 'Avoid Adverse Geology' are designed to:

Accepted Answer

Prevent destabilization of landforms that could trigger erosion, landslides, or habitat loss

Answer

These credits focus on avoiding construction activities that destabilize slopes, soils, or geological features in ways that damage natural systems and habitats.
