Oceanic plants and animals easily capture what they need for their daily life, which make them 'lazy' and 'slow'. Sea water removes waste from animals and plants. Sea water is cleaner than we can imagine. Because of the huge volume of ocean, the waste produced by oceanic organisms and even human activities can hardly get the sea water polluted.
The nitrogen cycle is as important in the ocean as it is on land. While the overall cycle is similar in both cases, there are different players and modes of transfer for nitrogen in the ocean. [81] Nitrogen enters the ocean through precipitation, runoff, or as N 2 from the atmosphere.
Marine biogenic calcification is the production of calcium carbonate by organisms in the global ocean.. Marine biogenic calcification is the biologically mediated process by which marine organisms produce and deposit calcium carbonate minerals to form skeletal structures or hard tissues.
Precipitation can seep into the ground and become part of groundwater systems used by plants and other organisms, or can runoff the surface to form lakes and rivers. Subterranean water can then seep into the ocean along with river discharges, rich with dissolved and particulate organic matter and other nutrients.
The reason lies in the highly hydrated Mg 2+ divalent ion, the second most abundant cation in seawater after Na +, known to be a strong inhibitor of CaCO 3 crystallization at the nucleation stage. [ 1 ] [ 2 ] The chemical conditions of the seawater must be notably high in magnesium content relative to calcium (high Mg/Ca ratio) for an aragonite ...
Seagrasses are recognized as some of the most important member to marine communities. It is the only true submerged angiosperm and can help determine the state of an ecosystem. [ 1 ] Seagrass helps identify the conditions of an ecosystem, as the presence of this plant aids the environment by: Stabilizing the water's bottom, providing shelter ...
Silicate, or silicic acid (H 4 SiO 4), is an important nutrient in the ocean. Unlike the other major nutrients such as phosphate , nitrate , or ammonium , which are needed by almost all marine plankton , silicate is an essential chemical requirement for very specific biota , including diatoms , radiolaria , silicoflagellates , and siliceous ...
Marine plants can be found in intertidal zones and shallow waters, such as seagrasses like eelgrass and turtle grass, Thalassia. These plants have adapted to the high salinity of the ocean environment. Light is only able to penetrate the top 200 metres (660 ft) so this is the only part of the sea where plants can grow. [77]
