• oceans are the largest ecosystems on
earth
• 70% of earth's surface is covered by
water
• 97% of earth's water supply comes from
the ocean
• ocean habitats range from
> dark & cold high pressure places
to
> warm & sandy beaches
• Marine ecosystems are based on salty
water
• different zones of the ocean supports
different types of life
> ex. sunny, shallow water ‐
phytoplankton & zooplankton
• Intertidal Zone‐ are where the ocean
meets the land
• Neritic Zone ‐ water is deeper and
warmer, organisms such as coral live
here; water is less than 200 meters deep
• Oceanic Zone ‐ deeper than 200 meters,
in between zone
• Benthic Zone ‐ ocean floor
• Polar Ice ‐ icy waters found around the
arctic ocean and the waters surrounding
Antarctica
• Estuary ‐ fresh water streams & rivers
spills into the ocean, where fresh water
& salt water constantly mix
• Tributary ‐ any stream of water that joins
another stream
> as more tributaries join they become
rivers
• Littoral Zone ‐ zone closest to the land
• Wetlands ‐ areas of land where water level is
near or above the surface of land for most of
the year
> Marsh ‐ treeless wetland where small
plants, such as cattails, grow
> Swamp ‐ wetland where trees & vines
grow & OGRES live
