"Abiotic" (not living) things are temperature, turbidity, pollution, destruction. Corals are very specific about the temperatures at which they can survive; reef corals especially so. Reef corals have zooxanthellae in their tissues, which require light. Turbidity reduces light. Pollution, such as heavy metals or halogenated hydrocarbons poison, the corals or their symbiots directly.Nutrient pollution, such as nitrates or phosphates, encourage growth of algae which can over grow the corals or increase turbidity. "Destruction" covers many things like storm surge, dredging, earthquakes, or boats dragging their anchors.
