Coral Reef

Biomes by: Julie Sepanski, Mary Irion

Location

Coral reefs are located in tropical oceans near the equator. The coral animals that build tropical reefs require sunlight found in clear , shallow ocean waters. Reef building corals also require warm water. Corals reefs are found in more than 100 countries around the world. Most reef are located between the Tropics of Cancer and Capricorn.

Weather

Coral reefs are non-moving structures that require warm tropical waters in order to grow. The majority of all Coral reefs are found in tropical and semi tropical areas. These areas provide the Coral with year round warm temperatures they need in order to survive. Experts have found that the Coral needs to be kept between 76-84 degrees Fahrenheit. If the water is warmer than the tiny algae will begin to die and the Coral will turn white, a process that is called Coral bleaching.

Some Different Types of Coral Reef

Coral Reefs

Variations

One type of coral reef can have a platy appearance where as in deeper waters there is more of a flattened mushroom shape. Another type looks like it has arms . This probably means there was a strong current at one point. Another kind has sharp dorsal spines that can penetrate human skin and cause sickness.( the picture on the right)

Coral Reef Environmental Adaptations

In order to collect the sunlight needed for photosynthesis, plants in coral reefs have larger cells. Sea grasses live in between the coral reefs, and they transfer nutrients to the coral. Mangroves grow behind the coral reefs. They grow above the sea water, and their roots protect from the sediment overpowering the coral.

Description of interdependency

Interdependcy is when something in an ecosystem relies on something else in the ecosystem to survive. An example of this is how that a clown fish relies on the anemone for a home to protect them. Coral reefs need clear water so they can get sunlight and they have to have sunlight so survive. Coral reefs have to have warm salt water to survive (68–90° F or 20–32° C)

Exotic Species

If I added a sea lion to the coral reef ecosystem then it would upset the balance of the entire ecosystem. If the sea lion population would grow to big then it would make all of the little fish start to decrease in population. Any exotic species that was introduced to an area will upset the balance of that certain ecosystem. The Lion fish will increase the population of the consumers on the trophic level above its own. The sea lion will make the little fish population decrease.

Native Species

The native species we are studying is the Sea Turtle because it is already in the ecosystem. If the Sea Turtle was taken out of the ecosystem then it would create an unbalance in the area. The producers and small fish would increase in population and nothing eats the sea turtle so no animal specie would decrease.
