Coral Bleaching occurs when, due to different circumstances, coral polyps die, turning the coral a pale white. Coral Bleaching occurs due to different circumstances. When the coral turns white, this doesn't mean that they are dead. Coral Polyps expel alge that live inside their tissue. Warm temperatures can cause coral bleaching to happen more often. When bleaching occurs, the alge inside the Coral leave, causing the coral to starve. Sometimes, the coral polyps die out after coral bleaching, causing the coral to soon erode away. Coral Bleaching can also affect the animals or fish that use the coral for protection from predators, if the coral polyps die due to the hot weather, and the coral erodes away, the animals have no more protection.

This is a video that shows a few scuba divers touring what happens when corals bleach.

Like a species that if it died it could kill all the other species. One species is coral. If coral died then the animals who lived there would have no protection and would be hunted to extinction ]]> 2018-01-12 22:02:20 UTC https://padlet.com/315870/kc9dgoesqky5/wish/221145169 529210 https://padlet.com/315870/kc9dgoesqky5/wish/221145393 Climate change is when carbon dioxide is released and the temperature/climate becomes warmer or colder, but usually warmer. Right now, the earth is suffering from a climate change. One example of climate change is in the ocean. Sea levels rise, ocean cirulation changes, and the frequency and intensity of tropical storms change.

Coral polyps are related to anemones and jellyfish. Coral is made up of several polyps. Polyps can ethier live individually or in a colony, where thousands of corals are created (coral reef). A coral polyp has a protected outside, due to the calcium and carbonate ions from the water around it. The coral polyps have a body structure that is similar to anemone. Polyps have a sack - like body, with a mouth surrounded by tentacles. Polyps are usually clear, with a white skeleton, but their zooxanthellae (tiny algae), that live inside their tissue give them their color, which causes the coral to gain its color. When polyps die, due to the hot weather, this causes "coral bleaching", when a coral turns completely white, without the polyps, they loose all their vibrant color and turn into a pale white. This can also happen due to other circumstances.]]> 2018-01-13 15:57:15 UTC https://padlet.com/315870/kc9dgoesqky5/wish/221193139 315870 https://padlet.com/315870/kc9dgoesqky5/wish/221292800 Ecological collapse is when the ecosystem suffers a large and possibly permanent drop in the maximum population of all organisms often resulting in mass extinction. One example is the Great Barrier Reef. Sections suffer from ecological collapse and are gettting bleached.]]> 2018-01-14 19:40:19 UTC https://padlet.com/315870/kc9dgoesqky5/wish/221292800 529210 https://padlet.com/315870/kc9dgoesqky5/wish/222209185 Coral Fluorescence is the reason why corals glow. It happens because of the absorption of light in one color and the emission in another.
Here is a video of someone shooting blue LED lights at the corals, and seeing their glow

Symbiosis is a beneficial relationship that corals and other animals have between one another, where both are at an advantage corals get protection and the other does also. Symbiosis helps many corals live longer and survive. Corals and other species have this relationship to survive at their advantage]]> 2018-01-17 19:45:02 UTC https://padlet.com/315870/kc9dgoesqky5/wish/222213404 1511983 https://padlet.com/315870/kc9dgoesqky5/wish/222221761 Renewable energy
Renewable Energy is energy from a source that is not depleted when used, such as wind or solar power. An example is coral reefs. Coral reef is made by the elimination or waste of different types of corals. Coral excreation is not wasteful and completely natural and a way to solve waste and pollution

Mass extinction is an event where a large decrease in a species starts happening rapidly. One example in coral reefs is coral reefs dying our rapidly in a huge widespread due to pollution and coral bleaching. Corals have been dying in huge numbers and rapidly and could lead to a mass extinction. Already many corals are going extinct]]> 2018-01-17 20:12:01 UTC https://padlet.com/315870/kc9dgoesqky5/wish/222224523
