you should do your home work by yourself but i am giving your answer last time
In ecology, the use, transformation, movement, and reuse of nutrients in ecosystems is referred to as nutrient cycling. Nutrient cycles are part of the earth’s Biogeochemistry (Refer Oxford Bibliographies article in Environmental Science). This movement of nutrients is a vital environmental function that influences and is influenced by the organisms inhabiting any given ecosystem. The aquatic systems, streams, lakes, and coastal areas transport and store nutrients and energy from local to continental scales over periods ranging from weeks to millennia. However, aquatic nutrient cycles are particularly vulnerable to change and, for example, altered nutrient inputs can degrade habitat quality and indirectly influence ecosystem productivity and diversity. This topic is partly covered in the Oxford Bibliographies in Environmental Science article River Pollution. For this reason, nutrient cycling is one of the most significant processes studied by aquatic ecosystem ecologists. Most studies consider different nutrient cycles and different ecosystems independently. In nature, however, terrestrial, freshwater, and marine systems are all connected by nutrient flows. Currently, human activities strongly influence nutrient cycles by removing nutrients from the land and discharging them into aquatic environments, leading to eutrophication of water sources. Furthermore, global change processes such as warming, deoxygenation, and acidification are also affecting cycling. Students or scientists interested in pursuing research in aquatic nutrient cycling will therefore have to integrate information from various fields including ecology, physiology, and biochemistry.
