CHARACTERISTICS
Marine ecosystem , complex of living organisims in the ocean enviroment .
Marine waters cover two-thirds of the Surface of the Earth.In some places the ocean is deeper than Mount Everest is high ; for example ,the Mariana Trench and the Tonga Trench in the western part of the pacific ocean reach depths in excess of 10,000 metres (32,800 feet ) . Within this ocean hábitat live a wide variety of organisims that have evolved in response to varous features of their environs.
HOW DOES INTERACT WITH HUMANS?
POSITIVE EFFECTS ⇨1 Stop wáter contamination in beaches.
2 Stop trawling fishing.
3 Take care of the meadow marine live.
4 keep the bottom of the sea clear.
NEGATIVE EFFECTS⇨1Trawling fishing damages all bottom of the sea.
2 humans extract sand for the beachand they destroy and damage poseidonia meadows.
3 wáter contamination also damages poseidonia.

food chain
1 primary producer ⇨plants (poseidonia)
2 consumers ⇨herbivores:they feed on the plant . example:Salema fish and Green turtle .
primary consumers:snails , slugs , starfish , urchins feed many algae live attached to poseidonia.
secundary consumers:variety of fish.Examples:espetones,cabrachos and octopus.
Top consumers:humans catch fish and then we eat the fish .
3 decomposers when plants and fish dead they are helping puting nutrients back into the bottom of the sea.Examples:fungi,bacteria and worms.
More information
1. Posidonia meadows habits the mediterranean sea.
2. In Spain it´s found in all the coastal provinces of the mediterranean.
3. Our ecosystem Project is abut Cabrera island in Balearic.
4. Poseidonians are ecosystems with high biodiversity.
