  1. Freshwater Ecosystem By: Alicia C. and Luke

  2. Examples: • Ponds, lakes, inland seas, wetlands, marshes, swamps, bogs, fens, creeks, steams, and rivers. • These places can be anywhere where there is a depression in the earth.

  3. Climate factors • Anywhere from -50F to 110F • The vegetation is mangroves and pickle weed, water lilies, algae, duckweed, cattails, reeves, and certain mosses

  4. The average rainfall is about 50in • This is enough to support the fresh water ecosystem

  5. Climate factors (cont) • Animals amphibians, reptiles, birds, furbearers, and insects • Amphibians: frogs and newts • Reptiles: snakes and alligators • Birds: bald eagle, craine, great blue heron • Furbearers: bobcat, beaver, deer, racoon, • Insects: drangon flies, Earth worm, mosquito, snails, spiders

  6. Limiting factors • Light oxygen temperature • Salinity food space ph nutrients and nitrates

  7. Net primary production • For lakes and streams 250gC/m²/yr

  8. location • Anywhere at any latittude outside of the polar regions

  9. Uses • Drinking • Energy and transportation • Boating and fishing • Fishermen and researchers • Hydroelectric power • Humans destroy habitat 40% of fish species live in fresh water • This has declined by 20% in the last 20 years

  10. Dam's block fish migration routes and destroy plants and animals • Pollution from runoff of agriculture and urban areas • Global warming produces devastating floods and droughts • Invasion of exotic species harm native animals and plants
