Coral reefs are very much the rainforests of the oceans . Not only are they diverse communities, but the coral skeletons – like trees – contain potentially long term records of climate. ... The analogy is often drawn to tropical rainforests, which are also extremely diverse and exist in nutrient poor conditions.
How are rainforests and reefs interconnected?
And the two sites are connected by more than happy proximity — the reef itself is built on the ancient rainforests of the past and is fed by underground creeks that run from the land out to sea, surfacing at the reef. The interconnection is profound.
How are coral reefs and rainforests similar?
Coral reefs are often called the “tropical rainforests of the sea” for their astounding richness of life. ... Like tropical rainforests, coral reefs are imperilled by human influences . Coral reefs are particularly fragile ecosystems, partly due to their sensitivity to water temperature.
In what way are trees and corals similar?
Trees tend to grow faster in warm and moist years. ... Many species of corals also have growth rings similar to those of trees. Scientists can extract cores from coral, and the coral growth rings can be used to reconstruct past climate in the tropical and subtropical regions. Corals grow faster in warmer waters.
What is happening to the coral reefs and rainforests?
Coral reefs are very much the rainforests of the oceans . Not only are they diverse communities, but the coral skeletons – like trees – contain potentially long term records of climate.

Do coral reefs produce oxygen?
Most corals, like other cnidarians, contain a symbiotic algae called zooxanthellae, within their gastrodermal cells. ... In return, the algae produce oxygen and help the coral to remove wastes.
Why are coral reefs in danger?
Increased ocean temperatures and changing ocean chemistry are the greatest global threats to coral reef ecosystems. These threats are caused by warmer atmospheric temperatures and increasing levels of carbon dioxide in seawater. As atmospheric temperatures rise, so do seawater temperatures.
What is killing coral reefs?
Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. ... Genetics is also becoming a larger area of coral research, giving scientists hope they might one day restore reefs with more heat tolerant coral.
