The Great Barrier Reef

Introduction:

The Great Barrier Reef is the world's largest coral reef. (1) It consists of a nexus of coral reefs, shoals and islets in near the Northeastern coast of Australia. It extends in a northwest-southeast direction for around 1,250 miles (2,000 km), at an offshore distance ranging from 10 to 100 miles (16 to 160 km) and has an area of 135,000 square miles (350,000 square km) allowing it to be the largest coral reef in the world. It is sometimes referred to as the largest structure built by living creatures. (2) Something that I would call the Burj Khalifa of the animals.

(4) The East Australian Current keeps the temperature in the region of the great barrier reef in this range as seen in the **picture**. This allows the coral in the Great Barrier Reef to thrive like none other. Corals are very sensitive to temperature and if the temperature increase then the zooxanthellae leaves their tissues making the coral unable to produce food on it's own, thus killing it. (5) If the temperature drops then a symbiotic algae present in the coral that helps it to get food lowers the amount of carbon transfer from the algae to the coral thus killing the coral. …show more content…
This way it can keep a look out and be safe from predators.(11)

Glass Shrimp and Chocolate Chip Sea Star: The glass shrimp will attach itself to the body of the chocolate chip sea star and since the glass shrimp as the name suggests is almost transparent it will take on the colour of the chocolate chip sea star and camouflage itself from predators.(12)

Parasitism:
Trematode and Snail:
The Trematode is a parasitic worm that can be found in many organism in the Great Barrier Reef, but when it attaches itself to a snail, the snail instead of reproducing snails reproduces parasites instead.(13)

Monogenea and Southern Fiddler Ray: Monogenea are parasitic flatworms that are virtually invisible to the human eye, it feeds off the skin of its host and is undetected by other predators.(14)

Human impacts on the Great Barrier Reef:

Overfishing:
Since fishing is now done by using nets attached to boats more fish are caught, leading to overfishing which leads to increasing fish prices and gaps in food chains which can affect whole ecosystems. For example if the prey is taken away then the Predator will starve to

    Ningaloo Reef Marine Ecosystem 1. Identify ten organisms from your chosen ecosystem and draw a food web to show trophic interactions between them. Within this food web, you must include and label a decomposer. Ten organisms that live in the Ningaloo Reef include the bottlenose dolphin, loggerhead turtle, tiger shark, whale shark, Southern Calamari squid, jellyfish, zooplankton, dugong, phytoplankton and seagrass. The decomposer in this food web is bacteria, which works to further break down the dead organic matter in the bodies of plant and animal organisms.…

    Two reasons why coral reefs are being threatened worldwide are because of tourists, who cause sewage to pollute the ocean and give nutrients to algae, step on corals, and destroy coral reefs with their boat anchors; overfishing causes the mass killing of sea urchins, which feed on algae, thus algae takes over the coral reefs and stunts their growth. B. The process of coral bleaching is when ocean temperatures become too warm, and the algae discharged from the coral causes the coral to begin a stress condition which turns them white; they are no longer the vibrant colors they used to be. When coral reefs lose their good health, organisms cannot live in/around them anymore, and the babies and eggs are exposed to predators, throwing off the aquatic ecosystem. C. 2 ways in which coral reefs can be protected from future destruction are by reducing the use of pesticides and fertilizers which enter the ocean through runoff, and by regulating overfishing with laws that set safe catching limits and controls on…

    Coral reefs provide shelter and food for more than 1 million plant and animal species, which is nearly one quarter of all known marine species. This number includes over 4,000 species of fish, 700 species of coral, and thousands of other plant and animal forms of life (Cesar, et al.). A single coral reef at its prime contains tens of thousands of species, housing some of the most dense and diverse communities of vertebrate animals in the world. Unfortunately, with the destruction that they face, very few coral reefs still resemble this condition, with corals and fishes less abundant than they were a few decades ago. Since we didn’t start studying coral reefs until they were already degrading, we aren’t sure about the historical biological baseline…

    “We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity” (Edward Owen Wilson, 2006). The Great Barrier Reef (GBR) was inscribed on the World Heritage List in 1981 and stretches for more than 2300 kilometres along the northeast coast of Australia, including an area of about 347 800 square kilometres of seabed. It is the largest coral reef ecosystem in the world with 2500 coral reefs and is home to more than 1500 species of fish and 5000 species of mollusc. Approximately 215 species of birds are found on its islands and cays. Despite the GBR being given World Heritage status the health of the GBR has declined to date.…

    It is also a breeding ground for animals such as six different species of turtles. The great the barrier reef is ancient and to some is dated back to around twenty million years ago. Sadly the great barrier reef is threatened by many things such as climate change, warmer ocean temperatures put stress on coral and lead to coral bleaching. The great barrier reef has experienced two mass coral bleaching events in 1998 and 2002, the bleaching was more severe in 2002, when aerial surveys showed that over more than 50% of the reef experienced coral bleaching. Sediment, nutrient and agriculture pesticide pollution from river catchment runoff is also affecting the reefs health.…

    The Great Barrier Reef (GBR) in Australia is known for the most amazing coral and fascinating sea life that live within it. The reef covers 134,364 square miles and is the home to over four hundred types of coral and five thousand types of fish and mollusk species. With warm water temperatures, the coral in the reef start to bleach losing its color. If the coral is under too much stress from the warm temperatures, the bleaching could become permanent and kill the coral. Typically, the temperatures will drop to give the coral time to recover from the damages but there has not been a change in the temperature.…

    A) What is a coral reef? Coral reefs are underwater ecosystems that are formed by many small animals called polyps, which through their ability to excrete calcium form the limestone skeleton that they live on. As coral reefs grow they can take on three structures fringing, barrier or atoll. The Reef located along the Queensland coastline is called the Great Barrier Reef as it is separated from the shoreline by a section of deep open water.…
