Final answer:
The correct analogy is 'surface mining : land ecosystem :: dredging : aquatic ecosystem,' showing a parallel between the effects of mining on different ecosystems.
Step-by-step explanation:
The analogy that would complete the given statement is: surface mining : land ecosystem :: dredging : aquatic ecosystem , option b is correct.
This comparison suggests that just as surface mining disrupts the terrestrial ecosystem, dredging similarly affects the aquatic ecosystem. It is important to consider the parallels between different types of mining activities and their respective environments to understand the broader impacts of extractive industries. As with mining, the analogy of oil extraction can be related to everyday life in that the preparation that precedes any task is crucial, and output is limited by the resources available.
