Prokaryotes are characterized by cells that are structurally _______________ compared to the cells found in the organisms of other kingdoms. they are important primary and secondary consumers that link plankton to large animals high on the food web. The _____ nutrient cycle is the basis for most of the biomass in all ecosystems. Special Attributes of Rays Superorder Batidoidimorpha of subclass Elasmobranchii consists of the rays, which includes skates and guitarfish. The presence of chlorophyll a and b in green algae leads some scientists to think that, The greatest challenge for a plant to adapt to living in the sea is. Sponges feed by drawing water into the oscula and them filtering it out through the sponge walls. Such traits include allozymes (Murphy et al. that assists chlorophyll a to capture light.                    In the five Kingdom System of classification non cellular Viruses, viroids, Prions … Home; Fishes Of The World; Fishes Of The World Any organism with a notochord and a dorsal nerve cord is classified in subphylum Vertebrata. Most fertilize their eggs internally. 1.water motion keeps sediments from accumulating on the coral, Coral ecosystems require water that is moderate motion and free of nutrients because, Eutrophication is one the biggest threats to coral ecosystems because it provides nutrients that allow plankton growth, depriving coral of sunlight, 1. under high pressure and temperature over long periods, Scientists think oil and natural gas form, nonporous rock traps oil and gas allowing a reserve to form, The physical characteristics of surrounding rock are important in the search for oil and gas because, Oil companies extract oil and natural gas from the seabed by, ice crystals containing methane found on the continental slope, they're difficult to get and dangerous to handle with current technology, Methane hydrates are not currently used as an energy source because, Besides iron and manganese, ferromanganese nodules consist of, About half of the world's magnesium production comes from, Products made from seawater evaporites include, Phosphorite deposits are the remains of marine organisms that live in areas of, offshore phosphorite deposits are too costly to recover, Land-based phosphorite deposits will likely remain the primary sources of phosphorous because, Hydrothermal vents and marine muds are potential sources of minerals and metals including.
