Which pair lists the two types of low wetlands?

• A. Marshes and Swamps
• B. Bogs and Fens
• C. Marshes and Bogs
• D. Swamps and Fens

Answer: (A)

Wetlands are often labeled by the plants that dominate them and how water sits in the landscape. Low wetlands sit in depressions or flat areas where water collects and the soils stay saturated. Marshes fit this setting with open water and mainly herbaceous plants like grasses and reeds, while swamps are also in low-lying areas but are dominated by woody vegetation such as trees and shrubs. Together, these two describe common low-lying wetlands because they share the same water-logged conditions, just with different plant communities. Bogs and fens are peat-forming wetlands with their own distinct characteristics. Bogs are usually acidic and dominated by mosses, while fens are fed by groundwater and have different nutrient conditions. That different peatland profile is why marshes and swamps are the best match for the two types of low wetlands.
