- FreshWater Ecosystem - Marine |
|
|
Fresh Water Ecosystem |
- only 3 percent of the earths water is 3% -Streams, Rivers, ponds, and lakes |
|
|
Streams and Rivers |
Mountain stream the water flows slowly at lower elevations, streams are warmer and often contain less oxygen, affecting the organisms that can live in them |
|
|
Ponds and lakes |
- Lakes are generally larger and deeper than ponds - Ponds are often shallow enough that sunlight can reach the bottom, allowing plant to grow |
|
|
Marine Ecosystems |
Saltwater |
|
|
Estuary |
Are found where the fresh water of a river meets the salt water of an ocean |
|
|
Internal zone |
Location - between the highest high-tide line and the lowest low-tide line Inhabitants - sea stars and barnacles survive sudden change in water levels and temperature that occur with high and low tides |
|
|
Neritic zone |
Location - Region of shallow water found below the low tides line and extending over the continental shelf Inhabitants - sunlight passes through the sallow water algae living here |
|
|
Surface zone, open ocean |
Location - Beyond the neritic zone about 200 meters deep Inhabitants - photosynthesis only occurs at the top tuna and swordfish live here |
|
|
Deep Zone Open Ocean |
Location - ocean floor Inhabitants - very little if sunlight even passes through animals feed on the remains of organisms that sink down, giant squid and anglerfish live here |
