7 INTERTIDAL ZONE – from high tide line to low tide line Pounding wavesChanges in temperatureChanges in salinityUnderwater & exposed to airAerial predatorsLittle food
8 NERITIC ZONE – low tide line to continental slope More life than any other zoneMajor fishing groundsSunlightNutrients from land and benthic zone (floor)
9 NERITIC ZONE SUNLIGHT & NUTRIENTS: Allows phytoplankton to grow Supports large number of zooplanktonPlankton is the basis of Ocean Food Webs
10 OCEANIC ZONE – from continental slope to continental slope Less sunlight & nutrients than Neritic ZoneSupports fewer organismsOrganisms are very different because of changes in water (Water Column)
11 BENTHIC ZONE – the ocean floor Deepest parts get no sunlight & is very coldMany organisms get food from material that sinks down from aboveSome organisms get energy from chemicals (chemosynthesis) that come from Hydrothermal vents.
