bog

– A bog is a freshwater wetland consisting mainly of partially decayed plant matter called peat.
– Sphagnum moss, reeds, sedges, heather and carnivorous plants are common bog plants.
– Bogs receive all or most of their water from precipitation rather than from runoff, groundwater or streams.
– Bogs are low in the nutrients needed for plant growth, a condition that is enhanced by acid forming peat mosses.  
– Peat bogs are carbon sinks, meaning they store enormous amounts of carbon, in a process called carbon sequestration. Carbon sequestration is a process where carbon dioxide is captured and removed from the atmosphere.
