ENST 2030 | 2026/2027 FINAL EXAM MASTERY GUIDE: 200
MULTIPLE-CHOICE QUESTIONS WITH RATIONALES COVERING
NON-RENEWABLE ENERGY, ECOLOGICAL FOOD WEBS,
MARKET-BASED POLLUTION CONTROLS, FEDERAL TOXIC
WASTE POLICY, AND THE KEY FIGURES & EVENTS THAT
SHAPED MODERN ENVIRONMENTALISM.
1. What are fossil fuels defined as?
A) Energy sources created from modern organic waste
B) Natural fuels formed in the geological past from remains of living
organisms
C) Synthetic fuels manufactured in laboratories
D) Renewable energy sources derived from sunlight
Correct Answer: B - Fossil fuels are specifically defined as natural fuels
formed in the geological past from the remains of living organisms,
taking millions of years to form.
2. How long did it take for organic matter to become coal, petroleum,
and natural gas?
A) Thousands of years
B) Hundreds of years
C) Millions of years
D) Billions of years
,Correct Answer: C - The organic matter from which fossil fuels are
derived took millions of years to become coal, petroleum, and natural
gas, making them non-renewable on human timescales.
3. What does it mean that fossil fuels are non-renewable?
A) They can be regenerated within a human lifetime
B) They are unlimited in supply
C) They cannot be replenished at the rate they are consumed
D) They are not useful as energy sources
Correct Answer: C - Fossil fuels are non-renewable because the
geological processes that create them take millions of years, far
exceeding human consumption rates.
4. What are trophic levels?
A) Levels of pollution in aquatic ecosystems
B) Parallels of energy assimilation and transfer within ecological food
webs
C) Layers of soil in forest ecosystems
D) Stages of plant growth in succession
Correct Answer: B - Trophic levels represent the hierarchical positions
in food webs where energy is assimilated and transferred between
organisms.
5. What trophic level do wolves occupy?
A) Primary consumers
,B) Secondary consumers
C) Apex predators/top carnivores
D) Decomposers
Correct Answer: C - Wolves are apex predators and top carnivores,
occupying the highest trophic level in their ecosystems.
6. What is rewilding?
A) A method of agricultural production
B) A practice of conservation restoring ecological functions and
evolutionary processes
C) A technique for urban development
D) A strategy for industrial pollution control
Correct Answer: B - Rewilding deliberately restores ecological functions
and evolutionary processes thought to have existed in past ecosystems,
often requiring reintroduction of large predators.
7. What does rewilding often require?
A) Removal of all native species
B) Reintroduction of large predators to ecosystems
C) Elimination of all human activity
D) Introduction of exotic species
Correct Answer: B - Rewilding frequently requires the reintroduction of
large predators to restore ecological balance and evolutionary
processes.
, 8. What is Cap and Trade?
A) A government regulation banning all emissions
B) A market-based system to manage environmental pollutants
C) A voluntary program for pollution reduction
D) A tax on all industrial production
Correct Answer: B - Cap and Trade is a market-based system where a
total limit is placed on emissions, and individuals or firms possess
transferable shares of that total.
9. How does Cap and Trade work?
A) By setting individual limits for each company
B) By placing a total limit on all emissions and allowing transferable
shares
C) By banning all polluting activities
D) By providing subsidies for clean energy
Correct Answer: B - The system works by placing a total limit on all
emissions in a jurisdiction, with individual people or firms possessing
transferable shares of that total.
10. What is the theoretical outcome of Cap and Trade?
A) Elimination of all pollution
B) The most efficient overall system to maintain and reduce pollutant
levels
C) Increased government control over industry
D) Reduction in economic growth
