On complete exhaustion of nitrate, oxygen may as last resort be obtained by reduction of sulphate yielding hydrogen sulphide causing foul smell and putrefied taste of water. Oligotrophic lakes are characterized by low nutrient values which limits the lake’s ability to support animal life. Eutrophic conditions are characterized by shallower waters and invasion of the lake by shoreline vegetation, replacement of green algae and diatoms with blue-green algae blooms, seasonal deficiencies of dissolved oxygen, and replacement of game fish by other species such as carp, suckers and catfish. Eutrophication derives from the Greek word. In natural Eutrophication, a lake is characterized by nutrient enrichment. It creates algal bloom, releases toxic chemicals that kill fish, birds and other aquatic animals. The term eutrophication refers to the natural and artificial addition of nutrients to lake waters and the effects of these added nutrients. (2). Cooper-sulphate and sodium arsenite are employed for killing algae and rooted planet respectively. The water is usually not good for drinking purpose. electrons in the outermost shell, Ans: d)Number of Studies have investigated the relative importance of denitrification or nitrification on N 2 O emissions; however, the linkage between N 2 O efflux and dissolved organic nitrogen (DON) and carbon (DOC) remains largely unknown.
