Deep-sea biology paul h yancey, phd professor of biology, whitman college --abyssal zone: the general ocean bottom or abyssal plain (2000-6000m average 4000m in a process called chemosynthesis (see link to onr site for more information) it has been claimed that these are the only ecosystems totally independent of sunlight. Quizzes science biology marine biology introduction to marine biology exam introduction to marine biology exam 22 questions | by abyssal zone d photic zone 16 tiny photosynthetic members of the plankton are called cellular respiration c chemosynthesis 19 the zone in the ocean where there is plenty of light. Other animals are able to use chemosynthesis for energy, such as those found around hydrothermal vents in addition to being intrinsically interesting, the abyssal plain may also provide clues to earlier life on earth. Most likely would be c for example if a seal dies it will sink to the abyssal zone where bacteria and other organisms that live down there feast on it. Interesting facts about the aphotic (midnight) zone of the ocean in what is known as chemosynthesis 6 most species inhabiting the aphotic zone rely on detritus (ie, the remains of dead organisms that sink to the ocean floor), while some rise to the biodiverse photic zone at night to feed interesting facts about the abyssal zone.
Ocean zones are layers within the oceans that contain distinctive plant and animal life they are sometimes referred to as ocean layers or environmental zones the ocean environment is divided into two broad categories, known as realms: the benthic realm (consisting of the seafloor) and the pelagic realm (consisting of the ocean waters. Fujikura k, kojima s, tamaki k et al (1999) the deepest chemosynthesis‐based community yet discovered from the hadal zone, 7326 m deep, in the japan trench marine ecology press series 190: 17–26. Chemosynthesis in general terms, and will be able to contrast chemosynthesis and photosynthesis abyssal zone hadal zone hydrothermal vent background information one of the major scientific discoveries of the last 100 years is the presence of extensive deep sea com. The process of making organic compounds from 1-2 carbon atom molecules (#co_2# or methane) using the oxidation of inorganic substances as a source of energychemo means chemical and synthesis means constructing meaning that it is the process in which carbohydrates are chemically produced by some organisms in the absence of sunlight.
No plants grow in the abyssal zone because it is too deep for sunlight to penetrate, and sunlight is necessary for plants to grow some organisms do live in this zone and survive through the use of chemosynthesis, which is energy that comes from chemical reactions the abyssal zone is located. The general ocean bottom or abyssal plain is the abyssal zone (2000-6000m average 4000m deep, and covering perhaps half of the entire planet) the deep trenches (about 6000m down to 11,000m or so in the mariana and mindanao/phillipine trenches) are sometimes called the hadal zone. Abyssal zone facts the abyssal zone is one of the many benthic zones we have highlighted to describe the deep oceans this particular zone is found at depths of 2,000 to 6,000 meters (6,560 to 19,680 feet) and stays in perpetual darkness.

The term deep sea creature refers to organisms that live below the photic zone of the ocean such as the abyssal or hadal zones, which, being thousands of meters below the surface, are almost completely devoid of light organisms can also use chemosynthesis to attract prey or to attract a mate. The giant tube worm, also known as riftia pachyptila, was totally unknown to science until researchers exploring the deep pacific ocean floor discovered strange, hydrothermal vents powered by volcanic heat, these vents recirculate water that seeps down through cracks or faults in the rock. The abyssal zone is a unique biome, as it is the only biome with organisms that survive from chemosynthesis, and has organisms that withstand immense pressure just to live in this biome also, this is the one of the only biomes in the world that contains organisms with bioluminescence, as shown in the finding nemo clip. The abyssal zone is one of the many benthic zones we have highlighted to describe the deep oceans this particular zone is found at depths of 2,000 to 6,000 meters (6,560 to 19,680 feet) and stays in perpetual darkness. What are the major characteristics of the abyssal zone earth science oceans ocean life 1 answer dean what is chemosynthesis what are the major marine life zones in which zone are the majority of the ocean species found why what is the great pacific garbage patch.
Deep sea hydrothermal vents redefining the requirements for life realized that bacteria were converting the toxic vent minerals into usable forms of energy through a process called chemosynthesis, providing food for other vent organisms. Chemosynthesis in general terms, and will be able to contrast chemosynthesis and photosynthesis abyssal zone hadal zone hydrothermal vent background information cold seeps are areas of the ocean floor where gases (such as methane and hydrogen sulfide) and oil seep out of sediments these areas are. A survey of deep-sea habitats from mesopelagic to abyssal to hydrocarbon seeps, and of deep-sea animals from viperfish to tubeworms hydrothermal vent zones have a density of organisms 10,000 to 100,000 times greater than found on the surrounding sea floor chemosynthesis is a process special bacteria use to produce energy without using. Interesting facts about the abyssal zone that'll startle you no compilation of interesting facts about the abyssal zone can be considered complete without the inclusion of topics like abyssal gigantism, chemosynthesis, and bioluminescence.
Hydrothermal vents: can anything survive this second-hand smoke occupying from the bathyal to the abyssal zone discovered by the deep-sea research vessel chemosynthesis is the process by which chemosynthetic bacteria use inorganic molecules, such as hydrogen sulphide. The abyssal zone corresponds to the large loose bottomed abyssal plains that extend beyond the rise of the continental slope at a depth of, between 5,000 and 6,000 metres biodiversity in the abyssal zone in these aphotic depths the pressure is very high and organic matter is rare organisms found in this environment, extremophiles, essentially feed by chemosynthesis or by decomposing the. Abyssal zone the ocean between about 4,000 and 5,000 meters (13,000 and 16,500 feet) deep acid rain rain containing acids and acid-forming compounds such as sulfur dioxide and oxides of nitrogen active transport the movement of molecules from a region of low concentration to a region of high concentration through a semipermeable membrane at. Abyssal zone this biome is located in the deepest part of the ocean the geology of this biome is very unique the floor is a sandy bottom, but on the ocean floor there are hydrothermal vents.
