Tooth bleaching

Argumentative Paper Coral reef bleaching is a serious problem that should be addressed immediately. Coral reef bleaching is an issue because of the damage done to the coral, and the damage done to the ecosystem associated with coral reefs. Some proposed solutions are that more areas of coral reefs should be protected, and sunscreens should be banned in and near the reefs. Coral reefs are living structures comprised of the exoskeletons of a marine organism known as polyps. Polyps are animals that

at risk from coral reef bleaching. Bleaching is bad for the coral because the endosymbiotic algae have a crucial role in the survival of coral. They provide energy in photosynthate. Bleaching is the lessening of zooxanthellate invertebrates. When the zooxanthellae are expelled, the tissues turn white. It generally happens when water is too warm, even though other things can provoke bleaching. Climate change is thought to play a role in increased events of coral bleaching around the world. It can

Coral Reef Bleaching Coral Reefs have a huge role in our environment, even though they only make up less than one percent of the oceans' ecosystems. They provide shelter for twenty-five percent of marine species, protect shorelines, support fishing industries, provide money from tourism, and could help scientists discover the next, big, medical breakthrough(Oceans and Coasts). Coral reefs are so biodiverse, they are referred to as ‘the Tropical Rainforests of the Oceans’. These diverse ecosystems

Sea Pens Description Sea pens are colonies of polyps( polyps: animals that have a fixed base,column like body, with mouth and tentacles.). Each polyps resembles a feathery quill. Sea pens are bilateral (bilateral: being able to divide into even halves). There is no typical weight for sea pens, but the height ranges from 2 inches to 6 feet. Sea pens have various colors. Their colors range from dark orange, yellow, and white. Habitat Sea pens are octocoral, which means they are a type of soft coral

Objectives: How do coral reefs form? What evidence do limestone deposits from coral reefs provide about Earth's history? Vocabulary: Algae: aquatic based plants that contains chlorophyll, lacking roots, stems, and leaves that can be anywhere from microscopic to having a long and distinguished form Calcium: the chemical element of atomic number 20, a soft gray metal Calcite: a white or colorless mineral consisting of calcium carbonate. It is a major constituent of sedimentary rocks such as limestone

As corals also use calcium-carbonate to build their structures, ocean acidification will also impede their growth by corroding pre-existing coral skeletons, whilst simultaneously decreasing the growth of new ones (Smithsonian, 2016). When the pH is lower, the corals have to use more energy to bind the carbonate building-blocks, hence the calcification rate is lower, and they lay down weaker skeletons (EPOCA, 2008). One study showed that, in acidifying conditions, coralline-algae, which build calcium-carbonate

grass and green algae. But enough talking about lagoons. The coral polyps issue is the death of the corals worldwide. The reason that the coral polyps are dying is because of the diseases overfishing, It’s basically a fancy way of saying coral bleaching. One-quarter of all marine species is found in coral reefs. The coral reefs are food to most species. The organisms that live in the coral polyps are being studied for new medicines. Each organism fits into the food web because well something

iconic to coral start to fade, thus the term coral bleaching. (Baker, Glynn and Riegal 2008) If the coral is left like this and its stressful conditions disappear it will eventually return to its vibrant colour, unfortunately if the stressor continues the coral will die. (Baker, Glynn and Riegal 2008) Reef building occurs over hundreds of years which makes the large scale coral bleaching all the more impactful on the underwater ecosystems. Bleaching events are so severe that an entire coral reef can

Coral bleaching occurs when the microscopic plants (zooxanthellae) are expelled by rising ocean temperature. When there are no microscopic plants such as zooxanthellae, the coral turns white and die. The studies show that throughout the worlds ocean, from the Florida Keys to the Great Barrier Reef of the Australia have been evidence of unique coral bleaching caused by the rising of ocean temperature. In the early 1980s the coral bleaching event has increased because of rapid increase of sea water

the world. It is made up of living organisms. • It is extremely biodiverse with different species of fish, coral, anemone, bivalves and worms. • Currently due to CO2 emissions changing the waters pH and climate, change warming up the water coral bleaching is occurring. This is when zooxanthellae are release from the symbiotic relationship with coral leading to the death of the coral. • There are preservation areas where tourist and people are not allowed to go. This is so the coral can grow again
