Transcript

  • 1. Kinds ofEcosystemThere arebasically twotypes ofecosystems;Terrestrial andAquatic. Allother sub-ecosystems fallunder these two.
  • 2. Terrestrial ecosystemsThese are found everywhere except water bodies.
  • 3. The Forest Ecosystem These are ecosystems where flora abundance is seen. They have a largenumber of living organisms in small area. So, the density of life in the forestecosystem is high.
  • 4. The Desert EcosystemDesert ecosystems are found in regions receiving an annual rainfall of less than 25cm. They occupyaround 17 percent of all land on the planet. Due to very high temperature, intense sunlight and lowwater availability, flora and fauna are very poorly developed and scarce. Vegetation is mainlybushes, shrubs, few grasses and rarely trees. Leaves and stems of these plants are modified toconserve water. The best known desert plants are the succulents like spiny leaved cacti. Animal lifeincludes insects, reptiles, birds, camels all of whom are adapted to the xeric (desert) conditions.
  • 5. The Grassland Ecosystem Grasslands are found in both temperate and tropical regions of the world but the ecosystems are slightly varying. This area mainly comprises of grasses with very little amount of shrubs and trees. Main vegetation is grasses, legumes and plants belonging to composite family. Many grazing animals, herbivores and insectivores are found in grasslands.
  • 6. The Mountain EcosystemMountain lands provide a scatteredbut diverse array of habitats inwhich a large range of plants andanimals are found. At higheraltitudes harsh environmentalconditions generally prevail, andonly treeless alpine vegetation isfound. The animals living here havethick fur coats from prevention fromcold and hibernate in wintermonths. Lower slopes commonly arecovered by coniferous forests.
  • 7. Aquatic EcosystemsAn aquatic ecosystem is anecosystem located in a body of water.It comprises aquatic fauna, flora andthe properties of water too. Thereare two types of aquatic ecosystems,Marine and freshwater.
  • 8. The Marine Ecosystem Marine ecosystems are the largest ecosystems with coverage of nearly 71% of the Earths surface and containing 97% of the planets water. The water in Marine ecosystems has salts and minerals dissolved in them in high amounts.
  • 9. Differentdivisions ofmarineecosystems are:
  • 10. OCEANICThe relativelyshallow part ofthe ocean thatlies over thecontinentalshelf
  • 11. ProfundalBottomor deepwater.
  • 12. Estuaries
  • 13. Coral reefs
  • 14. The Freshwater EcosystemIn contrast to the Marineecosystem, freshwaterecosystems only cover 0.8% ofthe Earths surface and contain0.009% of its total water.
  • 15. There are three basic types of freshwater ecosystems:Lentic: Still or slow-movingwater like pools,ponds, and lakes
  • 16. LoticFast-movingwater likestreamsand rivers
  • 17. Wetlands:Places where thesoil is saturated orinundated for atleast some time.
