It was later proved and demonstrated that benthic algae declined in the predicted regions where nutrients were ADDED. So, eutrophication with nutrients like N and P, needed to be controlled for the organisms to live with the needed amount of nutrients and still survive. Eutrophication was high at that time as well.
Oh my goodness look what we proved!
Some numbers you'll probably forget-- To maintain a healthy water ecosystem, N must be 700–1500 µg L−1 (units) while P must be 25–75 µg L−1 . N and P must not be too high, so they don’t kill off animals and cause damage through eutrophication, but they must be high enough to still provide necessary nutrients for organisms.
I'm so proud of how invested in this conversation you are. You may be wondering about the significance of this research! Well, this research is to provide new insights on how to control P and N nutrients in streams rather than just lakes! You should get some scientists as friends because they teach you all sorts of facts.
Knowing the measures of P and N that are safe for organisms and the eutrophication state of the streams is good for the world because we can prevent eutrophication but also make sure that organisms are safe in their environment!
Don't you want the fish to be safe?
Dad, you've been talking about eutrophication for six hours.
Alright, I guess we can go home. I'll tell you about another study that my dear friend conducted on gel electroflourisis on the way home! It's thrilling!
