本题解释: 正确答案:A
系统解析: 了解富营养化(Eutrophication )概念。
A:Eutrophication is the ecosystem response to the addition of artificial or natural substances, such as nitrates and phosphates from fertilizers or sewage, to an aquatic system.
Additional hardscapes can contribute to eutrophication and harm aquatic ecosystems and species.
Eutrophication is the process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates. These typically promote excessive growth of algae. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water of available oxygen, causing the death of other organisms, such as fish. Eutrophication is a natural, slow-aging process for a water body, but human activity greatly speeds up the process. |
