Coral Reefs

By: Zack Ward

Description

Coral reefs are large underwater structures composed of the skeletons of coral, that house thousands of different species.

Coral reefs are located in tropical oceans near the equator. The largest coral reef is the Great Barrier Reef in Australia. The second largest coral reef can be found off the coast of Belize, in Central America. Other reefs are found in Hawaii, the Red Sea, and other areas in tropical oceans.

Abiotic Factors

  • Temperature, Coral Reefs flourish in a temperature range of 77 to 84 degrees Fahrenheit
  • Nutrients, Coral Reefs only survive in clear water without much sediment in it
  • Light, A producer bacteria photosynthesizes which gives energy to the coral
  • Wave Motion, Takes away wastes and bring food

Biotic Factors

The Coral Reef is filled with dozens of communities but the most significant inter-species relationship is the symbiotic relationship between the coral polyp and the zooxanthellae. The polyp provides a home and carbon dioxide for the bacteria, while the zooxanthellae release oxygen and nutrients needed by the polyp for growth and development



-Adaptions


  • The clown fish has adapted to withstand the stings of the sea anemone to find a safe home which in turn helped the sea anemone
  • Sea grasses have adapted their roots to latch onto the ocean floor and withstand the currents
  • In general, the small fish in the coral reef have adapted from fast swimming bodies to more maneuverable bodies with pelvic and pectoral fins

Interactions

Importance

The importance of the coral reef it that it houses thousands of unique species that live nowhere else.

Human Impact

Pollution

  • Residue from oil mining
  • Fertilizer Run-off
  • Oil Spills
  • Garbage Dumping


-Over-Fishing

-Blast-Fishing
