Which of the following is a known bioaccumulator in aquatic ecosystems, meaning it can concentrate in organisms and move up the food chain, often found in areas affected by pollution?
-
A
Diatoms
-
B
Plankton
-
C

5
Decentralized finance (DeFi) platforms built on blockchains aim to disintermediate traditional financial systems. Some proponents suggest that the energy efficiency of certain blockchain technologies, like Proof-of-Stake (PoS), could reduce environmental impact. In terms of natural resource dependency, which of these ecosystems is most vulnerable to water scarcity exacerbated by climate change, a concern that resonates with the need for energy-efficient technologies?
-
A
Temperate Forests
-
B
Tropical Rainforests
-
C
Mediterranean Ecosystems
-
D
Boreal Forests
6
The scalability trilemma in blockchain refers to the challenge of achieving decentralization, security, and scalability simultaneously. Efforts to improve scalability can sometimes lead to trade-offs. Consider the impact of large-scale infrastructure development. Which of these natural phenomena, vital for global weather patterns and marine ecosystems, is being increasingly affected by ocean acidification, partly driven by increased CO2 emissions from industrial activity, including energy production?
-
A
Aurora Borealis
-
B
Tidal Waves
-
C
Coral Reef Bleaching
-
D
Geyser Eruptions
7
The creation of new units in some cryptocurrencies is often referred to as 'mining'. This term draws an analogy to the extraction of physical resources. Which of these animal species is critically endangered primarily due to habitat loss caused by deforestation, a process sometimes linked to the expansion of industries requiring significant land and energy resources?
-
A
African Elephant
-
B
Orangutan
-
C
Polar Bear
-
D
Great White Shark
8
The immutability of blockchain transactions has implications for record-keeping. In environmental science, accurate tracking of emissions and resource usage is crucial. Which of these is a naturally occurring greenhouse gas, whose atmospheric concentration is significantly influenced by human activities such as the burning of fossil fuels, a concern for industries that consume substantial energy?
-
A
Nitrogen
-
B
Oxygen
-
C
Carbon Dioxide
-
D
Argon
