Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Eutrophication is when ____ ?
A
A plant wilts due to lack of water
B
Fertilisers cause rivers and lakes to lack oxygen
C
Plants lack chlorophyll
D
Water and minerals flow into and out of a plant
Explanation: 

Detailed explanation-1: -Eutrophication is the process by which a body of water becomes enriched in dissolved nutrients (as phosphates), stimulating the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen.

Detailed explanation-2: -Eutrophication occurs when excessive nutrients cause a dense growth of algal blooms that can be seen. As algae ultimately die off and decompose, oxygen is consumed resulting in low levels of oxygen in the water.

Detailed explanation-3: -Eutrophication of lakes is caused by overenrichment with nutrients, principally phosphorus (5). Excess phosphorus inputs to lakes usually come from sewage, industrial discharges, and runoff from agriculture, construction sites, and urban areas.

Detailed explanation-4: -Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication-which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.

Detailed explanation-5: -When too much fertilizer enters the water, it can cause the natural process of eutrophication to speed up. Eutrophication causes algae growth to explode.
