One important source of water pollution caused by farming activities is called sedimentation. Sedimentation occurs when wind or water runoff carries soil particles and dumps them into a nearby lake or stream. Too much sediment can cloud the water, which reduces the amount of sunlight that reaches aquatic plants. It can also clog the gills of fish or smother fish larvae.
How does the structure identified in Part A contribute to the development of ideas in this section of the article?
It describes how farming activities have caused sedimentation throughout history.
It compares the effects of sedimentation on aquatic plants to the impact on fish.
It shows that because farming activities are polluting the water, sedimentation occurs.
It explains the steps that lead to water pollution.
