Marine mammals such as dolphins and seals, as well as sea birds, also act as tertiary consumers. While abiotic factorshave more to do with inanimate materials and elements, such as water, oxygen, sand, rocks and shells, the biotic factor of coral reefs has to do with the various creatures that inhabit the ecosystem and are part of the food web. an organism that obtains energy by feeding on organic materials. Many factors can be manipulated in this simplified reef model, including ocean temperature and pH, storm severity, and input of excess sediments and nutrients from logging, sewage, and agriculture. The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.) Some of the biotic factors that are specific to coral reefs are seaweed, squid, crab, minerals from dead organic substance, crustaceans,algae,and coral.

Along with coral, the marine … Temperature and sunlight are two abiotic factors found in nearly every ecosystem, but since the Great Barrier Reef is an aquatic ecosystem, it has some additional abiotic components, including buoyancy, viscosity, light penetration, salts, gases and water density. Hard Substance- Any type of rock or stone that is found on the ocean floor and is also used for coral to settle on and grow on. Many variables can be manipulated, included intensity of fishing, presence of black band and white band disease, and the presence of actual and potential invasive species. Light penetrates the ocean surface only about 20 meters. Some of the abiotic factors that are specific to coral reefs are oxygen, water , carbon dioxide, sand, rocks, shells, temperature,light, hard substance, and waves. a biotic without life. arms, and soft body.
