ENV SP Natural World & Ecology 4

Question 1

A sustainability professional evaluating a project near a coastal estuary should prioritize which ecological service provided by estuaries?

Accepted Answer

Nursery habitat for commercially important fish and protection of coastlines from storm surge

Answer

Carbon storage in deep-sea sediments

Answer

Freshwater recharge for inland aquifers

Answer

Primary production of terrestrial food webs

Question 2

Which of the following invasive species management strategies aligns best with Envision's Natural World principles?

Accepted Answer

Prioritizing mechanical and targeted removal integrated with native species restoration

Answer

Introducing a secondary invasive predator to control the primary invader

Answer

Applying broad-spectrum herbicides across all affected habitat indiscriminately

Answer

Leaving invasives in place to avoid additional soil disturbance

Question 3

What is the primary purpose of an Environmental Impact Assessment (EIA) in relation to infrastructure projects and natural systems?

Accepted Answer

To systematically identify, predict, and evaluate potential environmental effects before project approval

Answer

To calculate the financial cost of environmental mitigation measures

Answer

To certify that a project meets LEED or Envision sustainability standards

Answer

To establish legal liability for environmental damage post-construction

Question 4

The concept of 'ecosystem services' in infrastructure planning encompasses:

Accepted Answer

The benefits that functioning natural systems provide to human communities, such as clean water and pollination

Answer

Maintenance contracts for green infrastructure assets

Answer

Ecological monitoring services provided by environmental consultants

Answer

Utility services designed to mimic ecological processes

Question 5

A project minimizes light pollution to protect nocturnal wildlife. Which of the following best explains the ecological basis for this measure?

Accepted Answer

Artificial light at night disrupts circadian rhythms, navigation, and predator-prey dynamics for many species

Answer

Nighttime lighting increases heat island effects that harm cold-adapted species

Answer

Bright lights attract invasive insects that outcompete native pollinators

Answer

Light pollution reduces photosynthesis in plants adjacent to project areas

Question 6

In the context of the Envision framework, 'net zero ecological impact' means a project:

Accepted Answer

Fully offsets any habitat loss or degradation with equivalent ecological restoration elsewhere

Answer

Produces no greenhouse gas emissions during construction

Answer

Avoids all contact with sensitive species throughout its lifecycle

Answer

Uses only recycled materials to prevent resource extraction from natural lands

Question 7

Which factor most strongly determines the resilience of an ecosystem to disturbance events such as drought or pollution?

Accepted Answer

Biodiversity, including functional redundancy among species

Answer

The total biomass of vegetation present

Answer

The geographic size of the ecosystem

Answer

The proximity of the ecosystem to human settlements
