Where is a Coral
Reef
Located?

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. Tropical Oceans are Shown in

structure of the
Coral Reef

A coral reef is composed of calcium carbonate, or limestone.
This is absorbed from the water by colonies of coral polyps and coralline algae.
Most the underlying foundation of the reef is dead, made up of layer upon layer of coral skeletons.
The living reef is built over the top of this, by tiny coral polyps adding new limestone to the massive base structure.
The polyps make skeletons (or corallites) of calcium carbonate around themselves.
The beautiful colour of corals comes from the colourful tentacles of the coral polyps and the zooxanthellae algae that live in the tissues of many species.

There are many species of fish, turtles, corals, mollusk, sea snakes, sponges, polyps.

• The Plants:
•

Algae, Coral, anemone, sea grasses, sea Lillie.

• Parasites:

Many parasites feed off of corals and fish living in this ecosystem.

coral reef and its ecosystem Essay

The Coral Reef and its Ecosystems SCI-201-P1IP Clement Yedjou Colorado Technical University For my Phase 1 Individual project, I chose to do my research on the ecosystems of the Coral Reef since I have always had an interest in marine biology. Coral reef ecosystems are one of the oldest and versatile on earth, yet they are also among the most threatened of the ecosystems in the coast and as the human population expand, so do the threats to the reefs. The coral reefs can be located in clear…

Environmental Impact On Coral Reef Ecosystems

Ecosystem Ecology: Coral reef ecosystems have been subject to exceptional deprivation over the past few decades. Many environmental factors have been identified to influence coral reef bleaching and consequently lead to a cascade of events that pose a serious threat to the ecosystem. Perhaps the greatest threat to coral reef ecosystems is climate change. The warmer water surface and an increase in carbon dioxide initiated by global climate change impact coral reefs by stimulating coral bleaching…

Essay on Environmental Studies

SCIE210 Coral Reefs are one of the most interesting and colorful ecosystems to be found in the marine environment on the planet. Environmentalists are saying that coral reefs are disappearing due to the atmosphere changing and human behavior. This paper will discuss how the Abiotic and biotic components work together to make and keep coral reefs. Where might this type of ecosystem be located? Give one specific example. Coral ecosystems can be broadly divided into four…

ecosystems at risk Essay

Ecosystems at Risk - The Great Barrier Reef By Rhiannon Stewart-White Introduction: Every ecosystems functioning is dependent on the Earths four complex overlapping spheres, (the atmosphere, lithosphere, hydrosphere and the biosphere.) These linkages enable ecosystems to work in a state of dynamic equilibrium. An ecosystem is the intense link of biotic and abiotic environments. A major ecosystem and tourist attraction in Australia is The Great Barrier Reef, which roughly covers an amazing 2300…

Coral Reefs Essay

Coral Reefs Coral reefs, also knows as the “rainforests of the sea”, are extremely diverse habitats under the sea that are formed by Coral, an anthozoan in the phylum Cnidaria. Corals live in colonies of other individual coral, called polyps. Corals secrete a hard calcium carbonate skeleton from the base of each polyp. They use this skeleton to grow their community on and when threatened by a predator, they can contract into the structure for protection. Because polyps are always secreting…

Coral Reef Essay

Coral reefs are found in mostly tropical areas, but they also inhabit a few non-tropical places in the ocean, like the Red Sea. They are found all over the world. They have some threats, but are very important to the environment. Coral reefs have a huge economic value. They are also very important to the ecosystem. Coral is simple organisms that produce skeletons. Those skeletons are made of the compound calcium carbonate. Coral is very closely related to sea anemones and jelly fish. It can be either…

Valuing Coral Reefs

Throughout the years researchers have attempted to value coral reefs. One of the complications in valuing coral reefs is that its value includes three different kinds of values given to different ecosystem services according to Brander, van Beukering, and Cesar (2007). These different kind of values given to ecosystem services include direct use values (for instance recreational activities and diving, snorkelling etcetera), indirect use values (coastal protection and nurseries/habitats for fisheries)…

Coral Reef Anthropology

If you’ve ever visited a coral reef there is no doubt that its beauty, diversity and many sea inhabitants probably captivated you. My first experience snorkeling in Belize was exactly this. I travelled to Belize on an Alternative Service Break trip with a group of students and we worked on a sustainable agriculture project with local cacao farmers. We got to go snorkeling as a fun activity and break from all of our hard work. The snorkeling crew that lead our group throughout the excursion, let us…

What Is Overfishing Destroying A Marine Ecology?

fishing methods for years, with the major increase of resource overexploitation, coral reefs have been destroyed beyond repair. Overfishing affects the reef’s ecological balance and biodiversity. It has created a rapid decline in populations along various coral reefs as well as the degradation of coral ecosystems. Overfishing does not just affect one species, it has a domino effect. The variety of species in the coral reef all relies on one another and as soon as one species is destroyed, another one…

Great Barrier Reef Research Paper

Great Barrier Reef; it’s a land filled with the wonders of marine life and the beauty of biodiversity. A land where clear, crisp water can flow freely and fish can swim without the restriction of humans. At least that’s how many wish to imagine it. However, the current situation off of Australia’s northeastern coast is far from the picture-perfect image we all hold so dear. Human actions have damaged this beauty of nature to the point where it is nearly irreversible. Day by day the coral wonders have…
