Explanation:

Question 9

Cattails are commonly found in wetlands. Trout are fish that inhabit rivers/streams. Frogs can be found in wetlands. Otters are often found near rivers/streams and lakes/ponds but are more associated with rivers/streams. Great egrets can be found in wetlands. Salmon are anadromous fish that start in rivers/streams. Alligators are found in wetlands.

Eutrophication is mainly caused by an excessive input of nutrients like nitrogen and phosphorus, often from agricultural runoff or sewage discharge. Heavy - metal introduction is pollution but not a primary cause of eutrophication. Oxygen depletion is a result of eutrophication, not a cause. Excessive plant growth is a symptom of eutrophication, not the primary cause.

Answer:

Rivers/streams: trout, otters, salmon
Wetlands: cattails, frogs, great egrets, alligators
Lakes/ponds: (no clear - cut organism from the list exclusively for lakes/ponds)
