Document Summary

Population- group of organisms of the same species occupying a specific area: populations are w/ in communities. Ocean supports many distinctive marine communities: examples , rocky intertidal communities, seaweed communities, sand beach communities, salt marsh and estuary communities, coral reef communities, open ocean communities, deep sea floor communities, hydrothermal vent and cold seep communities. Exposure to air and sunlight is another source of intertidal stress: reason why motile organisms have the advantage over attached ones. Rocky intertidal zones: from top of rocks down to the bottom of the ocean, 1. Spray zone: where waves are breaking, this zone is at the highest high tide, 2. Intertidal zone: high tide lowest high tide (buckshot barnacle, middle tide highest low tide (hermit crabs) Coral reefs are the most densely populated and diverse communities: low tide lowest low tide (many species of plants/animals, coral reefs dying in the last 20 years, different types of organisms dying with it food web.
