29% of the coral reef died in just one year

67% dead in the northern reef

within the next 30 years most if not all of the coral will be dead

25% to 50% of reef is already dead

In about 25 years, the oceans will become too warm, corals will be bleached every year and won’t be able to survive.

global warming, because the ph. of the water is changing in some parts of the ocean. which is making the carbon dioxide dissolve in the water making it more acidic and bleaching coral reefs.

They house the fish and marine life of our oceans they also produce the oxygen in our ocean and clean out the carbon dioxide in our waters. They are like trees and filter the negative compounds of the ocean and chemicals when its sustainable.

These abiotic factors control if corals can even live in certain areas. If water temp or acidity gets too high then the corals will die at a quicker rate

The value of coral reefs has been estimated at 30 billion US dollars.

In the past 200 years alone, ocean water has become 30 percent more acidic

The problem is a huge problem their has been a huge spike in coral reef death and demoralization on our corals. Where from 1990-present we have killed doubled our coral and our temperature has gone 2 Fahrenheit higher and when you do that they die

The region is bounded by subtropical gyres of the North and South Pacific and the equatorial current system of the Eastern Pacific. An additional significant oceanographic feature of the region is the eastern Pacific warm pool, located along the Central American shelf. The oceanographic dynamics of the region are strongly influenced by low-latitude trade winds, topography (i.e.

Major abiotic factors that are affecting coral is the change in the climate because the climate is making the water to warm to the point the coral die. And when the corals are getting to much nutrients they end up dying.

The algae provide the coral with nutrients which helps the coral thrive and grow, and the coral also provides the algae with shelter and a place to kind of latch onto. Both organisms benefit from each other and help each other out.

coral is an organism that plays a crucial role in making habitats for other marine life. coral is made up of polyps, which are tiny coral creatures alike. Coral gives algae a habitat to grow and thrive by giving protection from sunlight, and shallow seas. Algae helps the coral by producing energy from photosynthesis, to improve their skeletons.

High salinity can result in decreased growth rates and low salinity can cause death.

The rising temperature level in oceans when you raise the ocean by 2 Celsius, The coral begans to rot and die because it simply cant handle the heat.

Then that’s when salt clarity becomes higher and so does ph level, and things like algae and clams start dying things that absorb that acidity start dying from a lack of home.

Then algae starts developing without planktons or clams to eat it and it over populates then just dies from algae not being able to eat anything else.

If the temp of water gets to high the corals will die and high salinity will result in low growth rates

temperature rising and falling stresses the coral polyps causing them to lose algae that live in the polyp's tissues.

What is coral:

animal, vegetable, and mineral

related to sea anemones - share the same structure (polyp)

- polyp: tin can open at one end; open end has a mouth ringed with tentacles

-tentacles have nematocysts (stinging cells) used to capture small organisms

- digestive and reproductive tissues are inside the polyp

- different than sea anemones because of their production of a mineral skeleton

Relationship:

Algae provides coral with nutrients

Coral provide algae with shelter
