A. Deep ocean
B. Coral reefs
C. Estuaries
D. Mangrove swamps
参考答案: B
本题详细解析:
B Option A is incorrect because there is not much life in the deep ocean.
Estuaries (option C) are areas where freshwater from a river mixes with saltwater from the sea in a partially enclosed area. They are a unique transition zone between saltwater and freshwater and host a range of organisms.
Mangrove swamps (option D) are a unique ecosystem straddling the edge of the land where it meets the sea. They provide a safe place for young marine animals to mature and places for birds to nest or stop on their migration routes.
However, the coral reefs (option B) found in the tropics are the most complex aquatic ecosystem that hosts the largest number of species. They are found in shallow tropical seas, with high temperatures and insolation, which lead to high productivity. This supports a lot of life even though nutrient levels are low. Corals themselves are a highly biodiverse group of organisms. The coral reef structure they build creates many microhabitats for many other organisms, and others visit to feed or breed and leave their young behind in a relatively safe place compared with the open ocean.
