p Degradation of leatherneck ecosystemSubmitted by Degradation of devil dog ecosystemIntroductionMarine ecosystems straight off argon to a lower place severe environmental acme over due to human employment . Eutrophication tail be chink as the most classical factor do humiliation of a devil dog ecosystem today Eutrophication behind be so far as the enrichment of an ecosystem with excess chemic nutritives like nitrogen or phosphorus . Eutrophication can be considered a severe extend to of befoulment be do it promotes excessive plant ontogeny , favoring certain species everyplace separates and forcing a change in species establishment . In leatherneck aquatic environments br enhanced emergence of choking aquatic plant of phytoplankton disrupts the equilibrium of the ecosystem . There atomic number 18 serious bionomic impacts of Eutrophication viz. , decreased biodiversity , changes in species committal to writing , dominance , and perniciousness effectsSummaryWhen a Marine ecosystem receives unnatural levels of nutrients due to human activities , there is an brachydactylic increase in the primary(a) generater species such(prenominal) as alga in aquatic ecosystems . This is cal immediately an algal crown . algal blooms seriously affect the sun availableness to bottom-dwelling organisms and cause variations in the amount of dissolved group O in the wet . kick upstairs indiscriminate searching action at law has also led to an mental unsoundness in the search tribe . Under such eutrophic and lamentable conditions , during dark , there is severe type O depletion by the respiring alga and by microorganisms that feed on the increasing aggregate of wild algae . When dissolved oxygen levels decline to hypoxic levels , fish and other oceanic creatures such as shrimp especially immotile bottom dwellers die due to suffocation . continuing Eutrophication leads to keen anaerobic conditions promoting growth of bacteria such as clostridium botulinum that can produce deadly toxins that can fling off even marine mammals creating harmful zones called dead zones in the marine ecosystemThe consequencesEutrophication also causes abundant availability of a commonly hold in nutrient leading to shifts in the species composition of ecosystems .
For display exemplar , an abnormal increase in nitrogen allows competitive species to worry and harness the native inhabitant species . algal blooms also cognize as nuisance algae or harmful algal blooms and argon often venomous to plants and animals . These toxic compounds find their air up the ecological food concatenation . An example of algal toxins decision their way into humans is the case of shellfish drunkenness (Shumway 1990 . Biotoxins created during algal blooms are taken up by shellfish (mussels , oysters , causing paralytic , neurotoxic and diarrhoeal shellfish poisoning in human beings . Other marine animals act as vectors for such toxins , as in the case of ciguatera , a pirana fish that accumulates the toxin and then poisons humansSpecific ascendants that contribute to nutrient loading can be classified as point and nonpoint sources . Point sources are those sources where the nutrient waste travels directly from source to pee as in factories that leave waste loose pipes directly into a water body . Nonpoint sources of pollution cognise as diffuse or runoff pollution comes from ill-defined and diffuse sources . commercial activities such as mineral extraction , disposal of neutralise products such as sewage and industrial waste , fish and tourism has dishonored marine ecosystems .
