In the Ocean Reef there are many abiotic and biotic factors. Would you like me to tell you some?Some Biotic factors that live in the Ocean Reef are all marine animals and plants- dolphins, fish, stingrays, starfish, shellfish, shrimps, seaweed, seagrasses, phytoplankton, zooplankton, sea urchins, sea cucumbers, nudibranchs, cunjevoi, coral, sea sponges etc. Some Abiotic factors that live in the Ocean Reef are all minerals, chemicals and substances - water, rocks, gases. I think that just about sums it up.
