are coral reefs living things?

Question

are coral reefs living organisms???write back as soons as possible

Answer 1

Yes,coral reefs are living things...

Answer 2

A coral reef is living only in the same sense that a sea shell is living. The single sea shell is the accumulation of calcium deposits made by a living organism which then resides there within it. The organism will die and the sea shell remains. The smaller coral organisms do the same thing. However, when they die and many other new ones build on top of those old "shells" or deposits so that a large formation is built over many years.
With a living coral the organisms are alive and the coral reef is growing. With a dead coral reef , the organisms are dead or dying and the calcium deposits remain like a massive skeleton.

Answer 3

The coral reef is full of tiny creatures in every little space. They are all part of the mass. There are loads of giant clams - don't put your hand or foot in one! It is very sensitive to heat and sunlight - it has to have the right balance, so global warming has been devastating. Coral dies when impacted, so a lot of tourist diving had to be stopped because they did not have any idea how to look after it - they would stand on it! In Bali there is a resort called Candidasa - it had a small coral reef round it which the locals hacked out to make into bricks - then the beach just fell into the sea so they decimated the tourist industry they were so dependent on! Whales would never get near it as it is in water that is too shallow I know I have gone off on a tangent, perhaps watching Finding Nemo would be useful - apparently it is accurate!

Answer 4

Yes - Coral reefs are aragonite structures produced by living organisms, found in shallow, tropical marine waters with little to no nutrients in the water. High nutrient levels such as that found in runoff from agricultural areas can harm the reef by encouraging the growth of algae. In most reefs, the predominant organisms are stony corals, colonial cnidarians that secrete an exoskeleton of calcium carbonate (limestone). The accumulation of skeletal material, broken and piled up by wave action and bioeroders, produces a massive calcareous formation that supports the living corals and a great variety of other animal and plant life. Although corals are found both in temperate and tropical waters, reefs are formed only in a zone extending at most from 30°N to 30°S of the equator; the reef-forming corals do not grow at depths of over 30 m (100 ft) or where the water temperature falls below 22 °C (72 °F).

Answer 5

Yes, they're tiny organisms that are vital to the ocean's ecosystem. Unfortunately, due to human carelessness, many coral reefs are dying out. If the coral die out, many of the oceans animal and plant life will also die because they are dependant on the reef for food and shelter.

Answer 6

no..they are not organisms...but the corals are living ones(considered to be animals in fact)...the difference is that the reefs are a conglomerate of corals..but you could say its living by a certain degree of interpretation.

Answer 7

Yes

Answer 8

Yes, Definately. They are tiny organisms in reefs.

They still live, but as human make more pollution, they are now endangered species.

They are still dying out...

Hope this helps.

Answer 9

yes the coral is alive. And so are all the fish that live on and near them. they breath and drink like all living things. They get oxygen from the water around them scince water (h2o) is 2% hydrogyn, 1% oxgen. Duh
