Some other Florida reefs vary from feet less than 2000.
The abiotic parts of the Florida Keys National Marine Sanctuary
There are many biotic things that are in this reef such as sand and rocks. Other abiotic factors are Hurricanes, sunlight, and currents. Hurricanes are abiotic factors that affect coral reefs by damaging them. Sunlight is an abiotic factor that provides light which is not living. Sand and rocks are also abiotic because they are nonliving things that live in this ecosystem. Temperature is an abiotic thing in this ecosystem.

The biotic factors of the coral reef
There are many animals in coral reefs. There are producers such as Phytoplankton, Coralline Algae, Filamentous Turf Algae, Zooxanthellae, and many species of seaweed. After the producers there are consumers such as larvae, benthic grazers, some corals, sea urchins, some crabs, green sea turtles, and herbivorous fish. After the consumers there is an apex predator such as a shark or a greater species. Last there are decomposers such as bacteria.
