Transcript of Coral Reefs
Processes Global Warming- the green house gases make the ocean warmer and the coral reefs climate then increases to were it bleached coral Coral Reefs Jessica Guinn and Feliza Bustos Temp: 77F - 84F
Nutrient Level: Low
light: important, used for photosynthesis
salinity: salty waters
depth: sallow waters, 60 meters, and some deeper
water movement: cleans waste and brings food buy Abiotic Factors El Nino- Warms up the water
La Nina- Cools down the water
Both kills the coral
Climate change can possibly be the end of the reefs Climate History Coriolis Effect Earth's Rotation and Coriolis Effect Geographic Locations

77F - 84 El Nino
-warmer waters = Coral Bleaching El Niño events bring unusually warm water which in results in coral bleaching, and La Niña brings cold water which also kill the coral El Nino and La Nina The currents curve and keep the climate at tropic level Biodiversity Coral Reefs is one of the most diverse on the planet, yet coral reefs cover less than one tenth of one percent of the ocean floor. Of the 34 recognized animal Phyla, 32 are found on coral reefs. DID YOU KNOW? Coral reefs are essential spawning, nursery, breeding, and feeding grounds for numerous organisms. Over 25 percent of the world's fish biodiversity, and between 9-12 percent of the world's total fisheries, are associated with coral reefs. While less well studied than shallow-water reefs, deep-sea coral communities are thought to support the greatest biodiversity in the deep ocean. Several deep-sea communities have already been identified as essential habitat for federally-managed species.

-Heterotroph Questions: 1. Where is the most abundant coral?
2. What questions would you ask if an interview with the companies' CEO, who have an impact on the pollution of coral reefs?
3. Why do you think certain groups strive to save the coral?
4. Can you asses the value or importance of knowledge about El Nino? Irrawaddy Dolphin
-Heterotroph Wrasse Fish-Heterotroph Decomposer Keystone Species Coral itself would be the keystone species, because disappearance would start a domino effect. Other species in the habitat would also disappear and become extinct without coral.
Endangered Species West Indian Manatee Staghorn Coral Hawksbill Turtle Endangerment Almost all destruction is caused by pollution. Prime examples include: Global Warming, Increased CO2, and Water Contamination Natural Capital Medical Research : 57,000 US$/hectare/year
Tourism : 1 million US$/hectare/year
Fisheries : of $3,181 US$/hectare/year
Protection : 189,000 US$/hectare/year Predictions If the pollution and destruction of coral reefs continues, then they will eventually die and bleach out. that being said, animals and other species living in this ecosystem will die too.
