Depending on the depth & availability of temperature & sunlight, the ocean is divided into different zones & this offers the presence of different type of organisms & the decomposers in each zone.
Intertidal zone - Lots of crabs, sea urchins, seaweed & starfish tend to live here.
Neritic zone - sea weeds, Crustaceans & large number of fishes are found in this zone.
Pelagic zone - This includes the photic zone, & aphotic zone.
Photic zone - Strengthen phytoplankton due to the availability of whales which feed on this phytoplankton are found here & sunlight.
Aphotic zone - This is the dark zone The sun’s light does not reach & hence is the home for many decomposers which feed on bits & pieces of dead stuff that sink down to the bottom.
Decomposers in the Ocean consist of marine worms, bacteria, & Marine Seaweed. Marine seaweed help protect marine life. It's also important because all of these things help eat away the dead organisms
