201. (b) explaining how human activities are posing a threat to coral reef communities (Because the second para tells about the various human activities which are a threat to coral reef communities)
202. (a) Coral reef communities may actually be more likely to thrive in waters that are relatively low in nutrients. (Because the "waste by-products all increase nutrient loads in these waters")
203. (a) provide an example of a characteristic sign of reef deterioration (Because "Typical symptoms of reef decline are destabilized herbivore populations and an increasing abundance of algae and filter-feeding animals")
204. (d) Waste by-products result in an increase in nutrient input to reef communities (Because "Agriculture, slash-and-burn land clearing, sewage disposal and manufacturing that creates waste by-products all increase nutrient loads in these waters")
205. (c) They are able to survive in an environment with limited food resources (Because the first para states that "how do clear, and thus nutrient-poor, waters support such prolific and productive communities?")
