Question

acts
c pig farmer has been collecting the pig manure in a shallow
hurricane matthew came through, it dumped a lot of rain in the
run-off of the manure. manure is waste from animals that is high
nd phosphorus and these levels in the local water supply
ramatically following this event leading to eutrophication.
tion is when the increased nitrogen in the water supply causes an
algae population growth eventually overpopulating and then
his boom and bust of the plants in the water hurts the rest of the

11 multiple choice 1 point
based on figures 1 and 2, do you think that the regulations on hog farming
have had a significant positive impact the amount of eutrophication in north
carolina waters
no, both nitrogen and phosphorous have significantly decreased
(more than 10%) which cancels out the effects of each so
eutrophication will stay the same.
yes, nitrogen levels have significantly decreased (more than 10%) so
eutrophication will significantly decrease.
yes, phosphorous levels have significantly decreased (more than 10%)
so eutrophication will significantly decrease.
no, phosphorous levels have not significantly decreased (more than
10%) so eutrophication will not significantly decrease

Explanation:

The question links eutrophication to nitrogen and phosphorus from hog farming, with the graph showing phosphorus levels (green line) have decreased below early eutrophication indicators, while the selected option aligns with this significant drop (more than 10%) leading to reduced eutrophication.

Answer:

Yes, Phosphorous levels have significantly decreased (more than 10%) so eutrophication will significantly decrease.
