Abiotic Factors
Here are some examples off abiotic factors in the Great Barrier Reef. Nutrients are an abiotic factor because they are essential for organisms to survive. Depth is an abiotic factor because it can determine what kinds of organisms are there. Light is an abiotic factor because coral needs light to survive because these are autotrophs. Light also affects how clearly an organism sees its predator or prey and how it does everyday things.
