Aquatic & Terrestrial Pollution
Which urban development strategy would have the largest impact on reducing heat island effects while simultaneously promoting biodiversity?
Creating additional park space equal to five percent of city land area.
Expanding public transportation networks throughout metropolitan areas.
Requiring green roofs across all new commercial building developments.
Incentivizing energy-efficient HVAC systems in large residential complexes.
Which legislation primarily aims to control air pollution at the national level in the United States?
The Clean Air Act
The Safe Drinking Water Act
The Endangered Species Act
The Clean Water Act
Which of the following best describes Zone of Toleration?
The range of abiotic factors in an ecosystem that organisms can tolerate.
The optimal conditions required for aquatic organisms to survive.
The area within an ecosystem where indicator species are present.
The specific range of pollutant levels that aquatic organisms can withstand.
What international agreement was established to reduce global greenhouse gas emissions?
The Kyoto Protocol
MARPOL (International Convention for the Prevention of Pollution from Ships)
The Montreal Protocol
CITES (The Convention on International Trade in Endangered Species)
Why might bioaccumulation be particularly dangerous for top predators like eagles or sharks?
Lower reproductive rates make them naturally resilient to chemical exposure
They have slower metabolisms that are less affected by pollutant dilution
Concentration increases at each trophic level, exposing them to higher toxin levels
Their wide-ranging diets include many unaffected prey items
What were the consequences of the Exxon Valdez oil spill?
Reduced biodiversity and the death of numerous animals.
Increased nutrient levels and eutrophication.
Formation of harmful algal blooms.
Acidification of the coastal waters.
What strategy could help prevent loss of biodiversity while enabling continuing resource extraction?
Introduction of genetically modified organisms to replace natural species
Unrestricted economic growth prioritized over conservation measures
Establishing extractive reserves where local communities manage sustainable harvesting
Stricter global bans on all forms of resource extraction

What does the oxygen sag curve represent?
The relationship between dissolved oxygen (DO) and the distance from a point source pollutant.
The rise and fall of oxygen concentrations.
The decrease in oxygen levels due to high biological oxygen demand.
The amount of dissolved oxygen (DO) different fish species need.
What is an indirect effect that invasive alien species typically have on native ecosystems?
They typically bring diseases that only affect their own population without harming natives.
They directly enhance biodiversity by introducing new prey items for native predators.
Incorrect answer
They may alter fire regimes or nutrient cycling processes thus transforming habitat structures.
What is a likely consequence of permafrost thawing due to global temperature rise?
Increased albedo effect due to ice melt leading to reduced solar radiation absorption.
Formation of new wetlands that serve as carbon sinks reducing atmospheric CO2 levels.
Enhanced plant growth due to nutrient release, leading to greater carbon sequestration.
Release of trapped methane contributing to enhanced greenhouse effect.
