Coral is not a living thing, it is the secretion of polyps. The polyp is a marine cylindrical coelenterate, which is automatically fixed on the calcareous bone pile of the ancestor coral in the white larval stage, the coral is the shell secreted by the polyp, the chemical composition of the coral is mainly CaCO3, which exists in the form of microcrystalline calcite aggregates, and there is a certain amount of organic matter in the composition, the form is mostly dendritic, with longitudinal stripes on it, and each single coral has concentric circles and radial stripes in cross-section, the color is often white, and there are a small amount of blue and black, and the coral is not only like a branch, The color is bright and beautiful, it can be used as an ornament, and it also has high medicinal value.

No, corals are made up of the excrement and carcasses of polyps and do not have the characteristics that life has, so they are not living things.

Corals are not living things, and the polyps attached to corals are.
The polyp is a marine cylindrical coelenterate. At the white larval stage, it is automatically fixed to the calcareous bone pile of the ancestor coral. The chemical composition of coral is mainly CaCO3, which exists in the form of microcrystalline calcite aggregates, and there is a certain amount of organic matter in the composition.
The form is mostly dendritic with longitudinal stripes on it.
Corals are piles up of the carcasses of polyps, not living things.
Polyps live in warm, shallow waters because sunlight is more likely to reach the bottom of the sea, which is conducive to the growth and reproduction of plankton.
In everyday life, people often confuse corals with polyps.
Coral is not a living thing because it does not have the characteristics of a living being:
Because living organisms have a common material base and a structural base.
Organisms all have a metabolic role. Metabolism is the basis for all life activities of living organisms. It is also the most basic characteristic of living beings.
Organisms are all stressful.
Organisms all have phenomena of growth, development, and reproduction.
Organisms have both genetic and mutated characteristics.
Organisms can adapt to a certain environment and can also affect the environment.
Biological life needs nutrients, and biological life activities need to breathe.
And those who meet the above characteristics are polyps, not corals.

No, it's the calcareous bones of the polyps.

Coral is abiotic, coral is the shell secreted by polyps, the chemical composition of coral is mainly CaCO3, in the form of microcrystalline calcite aggregates, there is a certain amount of organic matter in the composition, the form is mostly dendritic, there are longitudinal stripes on it, and each single coral has concentric circles and radial stripes in cross-section.
-
No, corals (non-living things) are formed by the accumulation of the shells of polyps (living things) after death, and there is no sign of life....There is a scientific basis for this
-
Corals are formed by the accumulation of coral poral corpses and excrement, and corals do not have the characteristics of living organisms; So it is not a living thing
Therefore, the answer is: no, coral is the accumulation of coral poral corpses, excrement, etc., and corals do not have biological characteristics.

Polyps are living beings, but corals are not.
Polyps are a general term for many groups of organisms in the phylum Coelenterates (now known as the phylum Cnidararians) and corals. It is a general term for a large group of marine cylindrical coelenterates, with a cylindrical body and eight or more tentacles, tentacles with mouths. They live in groups, combining into a group, where food enters through the mouth and food debris is expelled from the mouth, and they feed on the tiny plankton of the ocean.
There are some species of polyps that absorb calcium and carbon dioxide from seawater during their growth, and then secrete limestone, which becomes their own living shell, and the next generation of polyps will grow and reproduce on this calcareous material from generation to generation. This chain of calcareous materials is coral, which forms the support structure of the polyp. That is, corals are secretions of polyps, and corals are not living things.
Coral is like a tree branch, bright and beautiful in color, and can be used as an ornament. Gem-quality corals are red, pink, orange-red. The red color is due to the absorption of about 1% of the iron oxide in the seawater during the growth of the coral, and the black color is due to the presence of organic matter.
It has a vitreous to waxy luster, opaque to translucent.
The polyp has algae plants living with it, and these algae live on the waste products excreted by the polyps and provide oxygen to the polyps. Algae plants need sunlight and a warm environment to survive, and the higher the coral accumulation, the more conducive it is for algae plants to survive. Corals generally grow in an environment close to 28 years old, and the temperature has a greater impact on respiration than on photosynthesis, resulting in a decrease in the ratio of respiration and photosynthesis, especially when exposed to high temperatures, and the net photosynthetic products are also reduced.

Corals are not living things, polyps are living things. Coral is the shell secreted by polyps, the chemical composition of coral is mainly CaCO3 (calcium carbonate), in the form of microcrystalline calcite aggregates, there is a certain amount of organic matter in the composition, the form is mostly dendritic, there are longitudinal stripes on it, each single coral cross-section has concentric circles and radial stripes, the color is often white, there are also a small amount of blue and black.
Coral is not only like a tree branch, bright and beautiful, can be used as an ornament, and also has a high medicinal value, but its role in the environment is irreplaceable compared to the medicinal value.

Because you look at corals from different angles, there are different answers.
Wanrong, quarreling with Fu Yi, was snubbed, and became a complaining woman.
Yu Qian's death! The Battle of Tumubao was a turning point in the Ming Dynasty's transition from prosperity to decline, and when the Tile Spur Army attacked, Yu Qian took on the important task of protecting Beijing and won the victory, avoiding a repeat of the mistakes of the Song Dynasty. In the "Nangong Coup", he was killed by Xu Youzhen for rebellion because he supported Zhu Qizhen's son Zhu Jianshen. >>>More

The main body of the reef is made up of polyps. The polyp is a coelenterate in the ocean, which feeds on the small plankton in the ocean, and can absorb calcium and carbon dioxide from the seawater as it grows, and then secrete limestone, which becomes its own shell. Each individual polyp is the size of a grain of rice, and they live in groups of co-packs, metabolizing, growing and reproducing from generation to generation, while secreting limestone and bonding together. >>>More
Many people wonder why a person who can't speak a word clearly and wears a cap all day long can make so many people crazy, but for young people, it is strange that Jay Chou is not famous, because he doesn't know whether it is real or packaged image, it is simply the dream of modern young people - shy and introverted, but it creates a super cool feeling; has an enviable talent, but is low-key and not arrogant; The heart is self-proclaiming, but it is peaceful and ......All of this seems to have been born in response to the characteristics of this era, and it is exactly what today's students aspire to - almost every boy fantasizes about being such a person, and almost every girl fantasizes about finding such a boyfriend. Therefore, it is difficult for Jay Chou not to be popular; Therefore, a person born in 78 has become synonymous with the 80s; Therefore, Wu Zongxian tried his best to package him out back then, but now no one can hide his edge, let alone replace his position.
