Which of the following would be a result of eutrophication of nitrogen?

-undergrowth of water plants

-hypoxia, or low levels of oxygen

-Decreased decomposition

-inactivity of fertilizers

Eutrophication results from the increased amount of fertilizers in local water bodies like ponds or lakes. This actually results in the hypoxia or decreased oxygen content of the water bodies.

Option B

Eutrophication is seen in the water bodies that are located beside the agricultural fields. This actually occurs when rain water or water from different sources come into the water bodies. This leads to huge outgrowth of water weeds and this actually decreases oxygen content of water in two ways. Firstly, they consume a lot of oxygen dissolved in water. Secondly they block the sunlight entering inside water, thereby preventing photosynthesis from aquatic plants. Thus, the hypoxia exists in water which kills the aquatic animals like fishes etc. This condition can be prevented by application of several other ways like removing the weeds and purifying the water of the ponds etc. Else this will contaminate the whole environment.

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and colour.

explanation:

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
