What is eutrophication explain with reference to aquatic ecosystem?
What is eutrophication explain with reference to aquatic ecosystem?
Eutrophication (the overenrichment of aquatic ecosystems with nutrients leading to algal blooms and anoxic events) is a persistent condition of surface waters and a widespread environmental problem. This type of eutrophication is not reversible unless there are substantial changes in soil management.
What happens when eutrophication occurs?
Eutrophication is the process in which lakes receive nutrients (phosphorus and nitrogen) and sediment from the surrounding watershed and become more fertile and shallow. The additional nutrients cause algal blooms, additional plant growth and overall poor water quality, making the lake less suitable for recreation.
How do you explain eutrophication?
“Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”.
What human activities causes eutrophication?
Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. There are three main sources of anthropogenic nutrient input: erosion and leaching from fertilized agricultural areas, and sewage from cities and industrial waste water.
What is the end result of eutrophication of a body of water quizlet?
The end result of eutrophication is: Answers: increased nitrogen content of the water.
What is the principle called the conservation of matter?
Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
What is the meaning of conservation of matter?
The law of conservation of matter states that in any given system that is closed to the transfer of matter, the amount of matter in the system stays constant. Answer b: The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants.
What does conservation mean in science?
Conservation, study of the loss of Earth’s biological diversity and the ways this loss can be prevented. Biological diversity, or biodiversity, is the variety of life either in a particular place or on the entire planet Earth, including its ecosystems, species, populations, and genes.
