QuestionEcology / wetlands
Bog ecosystem wetland receives water only from:
- (a) Rain
- (b) Streams
- (c) Rivers
- (d) Groundwater
Answer: (a) Rain
A bog is ombrotrophic: it gets water only from precipitation (rain, snow). So it is acidic, nutrient-poor and dominated by Sphagnum moss and peat. A fen gets ground or surface water and is less acidic.
