Ocean's EcoSystem
What is an Ecosystem
a biological community of interacting organisms and
their physical environment.
What is unique about my
The ocean ecosystem, also known as the pelagic zone, is the
largest collective ecosystem on Earth. Open waters have the
greatest volume and depth of any living zone on the planet. The
basis of ocean life is plankton, which are microscopic plants that
move along ocean currents.
Coral Reefs
There are barrier reefs, fringing reefs and atolls. The last is often called an island when it is really a
reef. A coral reef needs sunlight to grow, that is why they hardly ever grow in waters deeper than 45
feet. They also are more likely to be found in tropical oceans, as the water is clearer and warmer.
Elephant Seal
The elephant seal is the most largest seal in the family member it
ways over 6,615 lbs (3,000 kg)
A male narwhal has the longest tooth. It's tooth can grow up to 9
inches longs
Marine Ecosystems

Estuarine ecosystems such as salt marshes, sea
grass, meadows, and mangrove forests.
Aquatic ecosystem
An aquatic ecosystem is an ecosystem in a body of

rtical range of any life zone. It includes the region above the continental shelf , called the neritic province, and the region beyond,
called the oceanic province. Gradations in light, temperature, water chemistry, nutrient content, and pressure result in a diversity
of environments that are filled by a large number of species. Life is found throughout the water column (that is, top to bottom),
but mostly in the photic zone, the region where sunlight makes photosynthesis possible. Organisms are also more abundant where
there are more nutrients: in the neritic, where nutrients wash off the land, and in upwelling zones, where relatively cold nutrient-
rich waters from the deep ocean rise to the surface. Pelagic life is dominated by plankton , mostly tiny organisms that move with
water currents. Photosynthesis by phytoplankton is directly or indirectly the primary food source for all marine life. The animals,
or zooplankton, that eat them may also be tiny, like krill, or they may be larger, like jellyfish, and able to make small, directed
system – a group of parts that work together as a unit.
stability – the condition that exists when the changes in a system over time cancel
each other out
ecosystem – groups of living things and the environment they live in
population – a group of the same species living in the same place at the same time
community – all the populations that live in the same area
