In return, the hermatypic coral provides the algal cells with nutrients and refuge. Furthermore, the coral get its nutrition from within, as well as, from feeding on small organisms. Floating food is captured by the polyp’s sticky, stinging tentacles. The most prominent members that make up the coral reefs are the corals. Corals are classified as the
ABSTRACT Coral reefs ecosystems have drastically changed over the past 40 years. The main reasons for the decline of coral reefs is due to weather and temperature changes, too much pollution, boats, and overfishing. As a result, coral reefs are considered an endangered species. Over 50% of the people in the Florida Keys rely on the coral reefs in one way or another. Many don’t realize that they provide humans with a source of income and more importantly, life for a wide diversity of marine animals.
Other animals include sponges, worms, sharks, snails, octopus, and more. All the marine life works together in symbiosis, helping and protecting each other. These animals obtain food and oxygen with the help of plants in the biome through photosynthesis. Some of the plants include zooxanthellae, algae, seagrasses, and phytoplankton. Another important factor to keeping the marine life alive are the warm currents and shallow waters.
Loss of coral reefs would be devastating to one of the most grand pools of biodiversity in the whole world They help seed the oceans and provide food to a complex web of organisms that lead all the way to man. They act as natural barriers to shorelines, and as they die, coastlines become more susceptible to damage and flooding; tropical storms and high waves would be the ones that could make the most damage if coral reefs were to disappear. Of course, not only we are the ones to be damaged by this, but other animals in the marine ecosystem too, like sharks. Sharks work in the ocean and in coral reefs by cycling nutrients between it and the open ocean, removing invasive species, and getting rid of weak fish carrying disease; if coral reefs were to disappear, then sharks would lose one of their main ways to obtain food and nutrients. And as we all know, if one animal disappears in an ecosystem, the organisms that consumed them would die and affect the food chain so
Containing an abundance of marine life consisting of over 3,000 individual reef systems and coral cays The Great Barrier Reef is one of the seven wonders of the natural world. Covering over 300,000 square kilometers and including a wide range of ocean depth it contains such biodiversity it makes The Great Barrier Reef one of the most complex ecosystems on Earth. Like any other ecosystem on Earth the Great Barrier Reef depends on both abiotic and biotic components to keep it functional and stable. Abiotic components are non-living factors that impact ecosystems such as temperatures of 77 degrees to 84 degrees Fahrenheit (25 degrees to 29 degrees Celsius). Certain coral reefs have progressed in order to survive outside this temperature range.
• LOCATION: Coral reefs tend to grow where there is a lot of water movement, bringing nutrients, oxygen and new species. Most reef-building corals cannot grow in waters shallow enough to expose them at high tide or deeper than 50 meters, making them highly sensitive to changing sea levels. Most of the coral reefs are situated off the eastern coast of Africa, off the southern coast of India, in the Red Sea, off the coasts of northeast and northwest Australia and on to Polynesia. Additionally, there are also coral reefs off the coast of Florida, USA, to the Caribbean, and down to Brazil. • HOW THEY ARE FORMED: A coral polyp is an invertebrate animal.
The reef, between 15 kilometres and 150 kilometres off shore and around 65 Km wide in some parts, is a gathering of brilliant, vivid coral providing divers with the most spectacular underwater experience imaginable. What Is The Great Barrier Reef? The Great Barrier Reef is a breeding area for humpback whales, migrating from the Antarctic and is also the habitat of a few endangered species including the Dugong (Sea Cow) and large Green Sea Turtle. In recognition of its significance, UNESCO listed the Great Barrier Reef as a World Heritage Site in 1981. Because of its natural beauty, both below and above the water's surface, the Great Barrier Reef has become one of the worlds most sought after tourist destinations.
Explain what a coral reef is and how it is created. A Coral Reef is Coral reefs are created by polyps that form around rocks and slowly start growing creating a reef after they grow for awhile. A coral reef is a rock type structure that is found in the ocean where fish are mostly found. Discuss the locations where coral reefs are commonly found and why this environment is important to its growth and development. Coral reefs are found in all three of the Earth's oceans that have portions in the tropics - the Atlantic, Pacific and Indian.
There are different types of mangroves; red, white, and black. The biggest cause of destruction of these mangrove forests is the human production of shrimp farms. Humans are cutting down mangrove in order to produce these great amounts of shrimp. Another way humans are effecting the mangroves is pollution, and other causes are the change in sea level and salinity, but this doesn’t quite involve humans. Oyster reefs are ecological communities that are packed with oysters and are very important in the marine life.
They also have cells that respond to light and touch (Gayora, 2014). Echinoderms play a vital role in marine environments where representatives are found in almost every ecosystem. Many are keystone species, playing significant and valuable roles (Dupont et al. 2010). Sand dollars and sea cucumbers burrow into the sand, providing more oxygen at greater depths of the sea floor.
