Ocean Abiotic Factors - National Geographic Society

Ocean Abiotic Factors, continued most ocean organisms are aerobic, meaning that they are oxygen-breathers. Some, like marine mammals and turtles, are air-breathers just like humans. Others, like fish, crustaceans, mollusks, and worms, are water-breathers and get their needed oxygen from the water.

CHAPTER SECTION 2 Marine Ecosystems

Two other abiotic factors that affect marine ecosystems are water depth and sunlight. The average depth of the oceans is 4,000 m, but sunlight does not reach deeper than 200 m. Producers that carry out photosynthesis, such as algae, can live only in water less than about 200 m deep.
