A. Expansion of habitat for large predators like killer whales.
B. Increase in fish populations.
C. Ocean acidification.
D. Reef-building organisms such as corals have increased in numbers.
参考答案: C
本题详细解析:
Carbon dioxide reacts with water to form carbonic acid. The carbon dioxide released by humans through the burning of fossil fuels has been dissolving in the oceans, causing acidification. Rising temperatures cause the loss of breeding grounds (Choice A) for marine fish and mammals. Local populations of fish and other marine animals are disappearing at double the rate of land-based species. (Choice B) The number of reef-building organisms has been reduced considerably. The concentration of carbonate ions which are needed to build the calcium carbonate shells of reef-building corals (Choice D) has decreased. The acidified oceans cause the dissolution of existing reefs and could make the corals disappear
