An abiotic factor in an ecosystem is one that is nonliving, but still has an effect on the living things within the ecosystem. The abiotic factor in the ocean would be the parts that are nonliving. All other animals and plants would be the biotic factors. The abiotic factor of the ocean would be the salt, sand, and water. The salt is primarily composed of sodium and chlorine, but there might also
. be some nitrogen and phosphorus mixed in. The water is made up of hydrogen and oxygen atoms. Other abiotic factors in the ocean would be sunlight as well as temperature. The deeper you go in the ocean the less sunlight there will be and the temperature will also drop. This makes the conditions less favorable for the biotic factors of the ocean, and only a few specialized types of organisms would survive there. Another important abiotic factor would be pollution. Things like garbage and oil spills can majorly affect the ocean ecosystem.
