1)which phrase best defines eutrophication
-a treatment that reduces pollution
-a lack of oxygen in a body of water
-an overgrowth of microorganisms
-an overabundance if nutrients
2)which statement about water remediation and stopping overproduction of nitrogen and phosphorus is correct
-water remediation is more cost effective than overproducing of nitrogen and phosphorus
-stopping overproducing of nitrogen and phosphorus
-water remediation leads to overproduction of nitrogen and phosphorus
-overproduction of nitrogen and phosphorus is the most effective method for water remediation
3)how does eutrophication harm aquatic environments
-it can increase the amount of oxygen dissolved in the water, which can be toxic to some organisms
-it can cause mixing of water in lakes and ponds, which can cause an over abundance of sunlights in the water
-it can cause an overpopulation of algae, which can lead to the death of other plants
4)freshwater is pumped into a pond that is experiencing eutrophication. which effect is the action likely to have
-the concentration of nutrients decreases, which improves the water quality in the pond
-the concentration of nutrients increases, which increases the available oxygen
-the concentration of nutrients increases, which can cause a toxic bloom of blue-green algae
-the concentration of nutrients decreases, which causes aquatic plants and animals to die
5)ultrasound waves can cause algae cells to sink to the bottom of a body of water. scientists apply ultrasound waves to a low suffering from eutrophication. which outcome should the scientists expect to observe in the lake?
-decreased oxygenation of lake water
-decreased photosynthesis by aquatic plants
-lower concentrations of nutrients
-fewer dead zones
