Marine Biomes- Aquatic Environment -Salt Water environment. -Lakes, Seas, Oceans, estuaries and coral reefs.- Varies in depth, temperature, chemical composition,

exposure to sunlight speed and direction of the current.

Estuaries • Opening of the mouth of a river that empties into the sea. • Salt and fresh water mixes forming large deposits of

sediments that accumulate on the riverbed. • Wildlife includes: - Fresh water organisms.- Species normally found in estuaries such as oysters and

sponges.

FUN FACT!• The Saint Lawrence is the only Estuary in Quebec

that stretches from Trois-Rivieres to Pointe-des-Monts!

Oceans AND Seas• Provide a wide variety of living conditions. • Marine habitats live divided according to the depth of the

water. Example:-200m- NO SUNLIGHT, therefore does not effect the environment. - completely dark, average temperature rarely exceeds 4 degrees Celsius.-Surface- Phytoplankton is eaten by all species like crustaceans, fish, jellyfish, mollusks, and some bird species and mammals.

Oceans AND Seas…Ocean Floor- Group of organisms called benthos, it is eaten by mollusks, crustaceans, and certain deep water fish species.

- These bottom-dwellers live in coastal areas between 0-350KM from the shore and at a depth of 200KM.

FUN FACT!• These areas are greatly effected by human

activity because 80% of fishing is done near the coasts!

Coral Reefs• They are the oldest biomes in the world, that date back

over 200 million years ago.• They contain reach biodiversity containing 500 000 and 2

000 000 plant and animal species.• Invertebrates that have a variety of shapes but all have a

central mouth and tentacles.• These corals are mostly found in tropical seas.• They form colonies that contain thousands of individual

species and measure several meters in height and diameter.

Coral Reefs…• Reefs are formed of calcium carbonate.• They provide a home, shelter and food to many species and

they are a major economic, social and cultural importance to the people who live near by.

• Pollution, overfishing, global warming and sedimentation are threatening the survival of these extraordinary biomes.

FUN FACT!• 20% of the worlds reefs have already been

destroyed.
