have returned to the Great Barrier Reef to measure the coral bleaching that has occurred this summer. Coral Bleaching is when corals are stressed from phenomena such as warmer-than-average waters for an extended period of time. The corals‚ which are actually little organisms called coral polyps‚ expel the algae that lend them their color and provide them with food‚ giving the coral a bleached appearance.

Autobiography: The Sea My family took a vacation the summer before sixth grade. We were in Maui‚ Hawaii to be exact‚ it was paradise. We walked to the beach from my family’s cabin everyday. As I looked around‚ the white sand felt scalding and the water was warm. The shore was filled with coral rocks‚ crashing waves and laughing children playing with the warm‚ wet sand. The water rose and fell‚ each time dissolving a sand castle into mud and making a child scream and run playfully from the water

The coral reef and desert ecosystem can be very similar or very different.The difference between the biotic and abiotic factors in the coral reef and the desert the ones in the coral reef live under water ‚and in the desert none of them live under water only some of the fish do. Some of the biotic animals in the coral reef are dolphins and seals. bivalves‚ gastropods‚ tunicates‚ sponges‚ polychaete and feather duster worms‚ some corals‚ sea urchins

Coral reefs are the home to more species than any other marine ecosystem‚ making them some of the most treasured and diverse ecosystems on the planet. They provide revenue for local communities by forming nurseries for fish‚ provide a destination for diving tours and fishing trips‚ break the power of waves to create a buffer that prevents erosion‚ property damage‚ and inundation‚ and protect the wetlands that line the coast‚ as well as ports and harbors. Many medicines are also now being developed

Our coral reefs along our Hawaiian Islands are in danger. The Hawaiian Coral Reefs suffer from degradation‚ which began about 100 years ago from westerners arriving and increasing. We need to do something to prevent our coral reefs from being in harm. They are suffering from oil spills‚ overfishing‚ bleaching‚ and careless tourists. In order for us to make a change‚ we have to research and find for solutions. Our reefs are complex and very diverse to the habitat. They are unique in many ways‚ like

Coral reefs are communities to the sea and home to many living creatures and different types of organisms‚ as well as about one-fourth of the oceans population. Coral reefs are made up of animals called polyps that will remain in one place‚ acting as the main structure of the reef itself‚ these animals have a hard almost skeleton like structure. Scientists who study coral reefs have categorized them into three different types of reefs; Barrier reefs‚ Atolls‚ and Fringing reefs. Coral reefs are put

Coral Bleaching Coral reefs deliver ecosystem services to tourism‚ fisheries and shoreline protection and often called “rainforests of the sea”. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. Coral reefs grow best in warm‚ shallow‚ clear‚ sunny and agitated waters. However‚ coral reefs are fragile ecosystems‚ partly because they are very sensitive to water temperature. They are under threat from climate change‚ oceanic acidification‚ blast

The Decrease of Coral Reefs Taylah Bruce Science 10.3 The Decrease of Coral Reefs In Australia‚ particularly‚ the rapid decrease of coral is becoming a vast issue. Our most prominent body of coral‚ The Great Barrier Reef‚ is facing annual bleaching within the next twenty years due to warmer‚ more acidic seas. It has alerted scientists all over the world of the future we face and many have come together in hope of conserving this amazing natural wonder and the millions of marine life that

* Coral reefs are underwater structures made from calcium carbonate secreted by corals. Coral reefs are colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. The polyps are like tiny sea anemones‚ to which they are closely related. * Coral reef ecosystems support a variety of human needs. They are important for subsistence‚ fisheries‚ tourism‚ shoreline protection‚ and
