Uh we're told that when organic waste is dumped into a pond, the oxidation process that takes place reduces the ponds oxygen content. However, given time nature where we started the african contents to its natural level in the phonograph uh p uh gives the I guess I I call it why here, why why it gives the actual content as the percent of its normal level. Two days after organic police has been dumped in the fund explained the significance of the inflection point. So we the organic goes waste goes in and so it starts using up some oxygen to decay um as it acted ISES. And then we get to a minimum point, the level of the uh the oxygen levels stops going down. Um And that's probably when the bacteria basically, you know, there's a there's uh basically because it wants to be so much oxygen absorbed in the water. There is constantly being some more then. But at some point around here the amount that's being drawn in from the surface overcomes. That's what's being used by the organic waste. And so we turn around and then it starts building up again. And now at at this point basically we get this inflection point I think basically says the radar change has an extreme at this. So this is where kind of the rate of change um is the maximum um As you know, as far as it's it's increasing. But so here the rate of change is decreasing and then here the rate of change is increasing. No no the rate of change goes from increasing here to decrease in here. So it's negative here, negative negative then turns around positive, but then it starts to decrease. Um And what what that is is basically, you know, it's a saturation effect, right? Um It's probably something where the more oxygen that's in there, the less that that is absorbed it and you know the rate of absorption. So that's where basically we have this um The rate now has a has a change where we now are the rate of change of why starts to decrease. And again, there's a maximum here where this is probably maybe this point here is where the oh the organic waste has been uh has been oxidized. Now, it's just a matter of you know, absorbing oxygen through the surface of the water.
