How does coral reefs help the ocean?
Coral reefs provide a buffer, protecting our coasts from waves, storms, and floods. Corals form barriers to protect the shoreline from waves and storms. The coral reef structure buffers shorelines against waves, storms, and floods, helping to prevent loss of life, property damage, and erosion.
What are 3 reasons that coral reefs are so important?
protect coastlines from the damaging effects of wave action and tropical storms. provide habitats and shelter for many marine organisms. are the source of nitrogen and other essential nutrients for marine food chains. assist in carbon and nitrogen fixing.
Do coral reefs clean the ocean?
Coral reefs are nature's water filtration system Many individual corals and sponges consume particles found in the ocean. In turn, this enhances the clarity and quality of the ocean's waters. Clean and clear water makes our beaches more beautiful and also allows coral reefs to continue to thrive.
How does coral help the water?
Water filtration Coral reefs help keep our near shore waters clean from pollution. Many corals and sponges are filter feeders, meaning they consume particulate matter (pollutants that do not dissolve in water) in the water.
What would happen if there were no coral reefs?
If coral reefs disappeared, essential food, shelter and spawning grounds for fish and other marine organisms would cease to exist, and biodiversity would greatly suffer as a consequence. Marine food-webs would be altered, and many economically important species would disappear.

Several attempts have been made to estimate the value of coral reefs in terms of dollars.
Why are coral reefs called rainforests?
Coral reefs are often called the rainforests of the sea, both due to the vast amount of species they harbour, and to the high productivity they yield . Aside from the hundreds of species of coral, reefs support extraordinary biodiversity and are home to a multitude of different types of fish, invertebrates and sea mammals.

How are coral reefs formed?
Corals reefs are formed over a process of thousands of years. Each coral reef is made up of colonies of tiny animals called polyps. Each polyp produces calcium carbonate, which makes up their skeleton and protects corals internal bodies; similar to how our skeleton protects our organs.
Why do corals die in warm water?
Rising water temperatures: Corals thrive in relatively warm water, but when water temperatures rise too high, the zooxanthellae are forced to leave. Since these algae give the corals color, when they leave the coral becomes white, appearing bleached.This coral bleaching can cause the reef to die.
What are the main causes of coral reefs?
Stressors to coral reefs are: 1 Rising water temperatures: Corals thrive in relatively warm water, but when water temperatures rise too high, the zooxanthellae are forced to leave. Since these algae give the corals color, when they leave the coral becomes white, appearing bleached.This coral bleaching can cause the reef to die. 2 Ocean acidification: Ocean acidification can affect coral health by making less calcium carbonate available in ocean waters, making it harder for corals to form their skeletons. 3 Predation: Some species can cause damage to coral reefs, like damsel fish and crown of thorn starfish. While they may not be invasive, outbreaks of these species can wreak havoc on reefs. 4 Overfishing: Coral reef ecosystems support an abundance of species, but overfishing can deplete these populations and effect the entire ecosystem. 5 Recreational Impacts: Boat groundings and anchors can harm corals by breaking or scarring them. Sunscreens that include certain chemicals, harm corals reefs and other plants and animals that live in the ocean. Protect yourself and the reef by covering up or wearing mineral-based sunscreens.
Why are corals bleached?
Coral Bleaching Monitoring on Guam. In response to stresses such as higher water temperatures, corals can lose the symbiotic microscopic algae (which provides up to 95% of the coral’s nutrition) from their tissues causing them to look white or "bleached.". If favorable conditions return, corals can sometimes recover.

Without these important habitats in which to thrive, fish and sea life will cease to exist. Coral reefs protect coasts from strong currents and waves.
How do coral reefs affect the ocean?
Coral’s limestone shell is formed by the ocean’s processing of carbon dioxide. Without coral the amount of carbon dioxide in the ocean rises, which in turn, affects all living things on Earth. Coral reefs are an important food source for humans.
What would happen if there were no coral reefs?
Without coral reefs many of the world’s most fragile, coastal ecosystems would be unable to thrive. Reefs can not exist in murky or polluted waters. Many individual corals and sponges consume particles found in the ocean. In turn, this enhances the clarity and quality of the ocean’s waters.
Why are fish important to humans?

Why are coral reefs considered the "rainforests of the sea"?
Because of the diversity of life found in the habitats created by corals, reefs are often called the "rainforests of the sea." About 25% of the ocean's fish depend on healthy coral reefs. Fishes and other organisms shelter, find food, reproduce, and rear their young in the many nooks and crannies formed by corals. The Northwest Hawaiian Island coral reefs, which are part of the Papahānaumokuākea National Marine Monument, provide an example of the diversity of life associated with shallow-water reef ecosystems. This area supports more than 7,000 species of fishes, invertebrates, plants, sea turtles, birds, and marine mammals. Deep water reefs or mounds are less well known, but also support a wide array of sea life in a comparatively barren world.
