Presentation on theme: "Aquatic Ecosystems. Marine Ecosystem The Ocean can be divided into zones Intertidal zone – strip of land between high and low tide lines (changes in moisture,"— Presentation transcript:

1 Aquatic Ecosystems

2 Marine Ecosystem The Ocean can be divided into zones Intertidal zone – strip of land between high and low tide lines (changes in moisture, salinity, temperature) Neritic zone – extends from intertidal out to the edge of the continental shelf Bathyal zone – from the edge of the neritic to the base of the continental shelf (turbid, murky, high pressure) Abyssal zone - below 2000 meters (no light, chemosynthetic)

3 Coastal Water habitats Coral Reefs Kelp Forests

4 Estuaries & Fresh Water Estuary – a partially closed body of water where a river flows into an ocean Carries high levels of nutrients from inland areas Highly productive areas

5 Freshwater Eccosystems Watershed – a region of land that drains into a river

6 Fresh water zones Littoral zone – located between high and low water marks along the shoreline Limnetic zone - open water farther out from shore Benthic zone – lake or pond bottom (less sunlight)
