Transcript of bog ecosystem

Food Chain Food Chain Food Chain sphagnum moss Producers blueberries cranberries Primary Consumers flies beavers butterflies Secondary Consumers pitcher plants dragonflies bullfrogs spotted salamanders snapping turtles red winged hawk muskrat Tertiary Consumers Peat: A brown, soil-like material characteristic of boggy, acid ground, consisting of partly decomposed vegetable matter. Bog Paludification Grass pink Showy lady's slipper Stemless lady's slipper Large yellow lady's slipper Bog Ecosystem Pitcher Plant Round-leaved Sundew Dried Peat Bogs consist of spongy peat deposits, acidic waters, and a floor covered by sphagnum moss Bogs receive most of their water from precipitation Bogs are low in the nutrients plants need to grow Bogs are mostly distributed in the northern hemisphere Locations The world's largest bog covers more than a million square kilometres which is in the Western Siberian Lowlands in Russia The largest bog in the southern hemisphere is the Magellanic Moorland spreading 44,000 square kilometers Development Terrestrialization is when sphagnum moss grows over a lake or pond and slowly fills it Paludification is when sphagnum moss goes over dry land and prevents water from leaving the surface A lot of acidic peat deposits build up in both The characteristics in bogs result in plants and animals with adaptions to low nutrient levels, waterlogged conditions, and acidic waters Plants The Pitcher Plant which has a purple or yellow flower rising on a tall stalk from a rosette of pitcher-shaped leaves
They are well-fitted with water and a sticky fluid that drown insects The Round-leaved Sundew has long-stalked round leaves that lie close to the ground and are covered with hairs that emit droplets of sticky liquid and can bend inward to trap insects they attract The Grass Pink, the Stemless Lady's Slipper or Moccasin Flower, the Large Yellow Lady’s slipper, and the Showy Lady’s slipper have beautiful and unusual flowers They have been almost exterminated by greedy pickers and collectors Ecological Function Bogs prevent downstream flooding by absorbing precipitation Bogs provide habitat to animals threatened by humans and support some of the most interesting plants. Peat Usage Peat is used for fuel in Finland, Scotland, Germany, Russia, and Ireland
Over 20% of home heat in Ireland comes from peat Russia exports peat for fuel at more than 90 million metric tons per year Bord na Mona was one of the first companies to mechanically harvest peat Peat can also be used as a soil amendment Once peat is extracted, it is difficult to restore the bog because bogs collect peat slowly 90% of the bogs in England have been damaged or destroyed THE END
