Basic classification
Marine biological community is also divided into several bands like a lake group:
1 tide band (ittor zo-neb) ), Is the area in contact with land. Although the organism in the belt is almost a marine life, it is actually a community interlaced area between the sea and indi, which is characterized by a periodic tide. Bios living in the tidal zone except for the impact of the waves, it is necessary to experience the temperature and water mask and exposure, develop many interesting forms and physiological adaptation. The underlying creature of the tide belt is different from the substrate to the sand, rock and silt differentiation into different types.

3 Shallow Hai Rings along the continental slope as a half-deep kernel, and most of the ocean is a deep sea zone (ABYSSAL ZONE). The environmental conditions of the deep kernel are stable, no light, temperature is around 0 ~ 4 ° C, and the chemical composition of seawater is also stable. The bottom soil is soft and picked, the pressure is very large (the water depth is 10 meters, that is, 1 atmospheric pressure ). The food conditions are harsh, and the food particles are completely rely on the upper food particles because there is no photoresist in the deep sea. Due to the light, deep sea animal visual organs, or have a shiny organ, there are also large eyes, located in Chang Bing, and the weak light feeling ability. Adapt to the characteristics such as high pressure, such as thin and perforated skin, no strong bones and strong muscles.
4 Ocean band, from the coast to the broader line of the open ocean, deep into the sun. The ocean area is large, but the water environment is quite consistent, only water temperature changes, especially the distribution of warmth and cold flow. The ocean lacks animal concealed, but the protective color is obvious.
Biological community type
mangroves, coral reefs, and horsetail sea are special biological community types in the ocean. Hepair Bay is a special ecosystem of the mainland water system into the ocean. Since many richer land is in terms of human landland transportation, it is very deeply disturbed by human activities. It is also easy to appear in Chi Lake, and River Ecology is an important research area.
Special Biological Community
Recently, some scholars have found some special biological communities when examining deep-sea creatures, and it is located around the Central Sea Central Harbor near the Galapogos Islands. The water flow temperature released by the crater is higher than the surrounding 200 ° C, and the exotic creatures in the never known as the biological community are habitally, such as 1/3 meter long clams and 3 meters long worms. These organisms are synthetic bacteria that produce organic matter by sulfide and reduction CO2, and consist of adenosine triphosphate. It is difficult to believe that these bacteria can survive at high temperatures 200 ° C.
