N and P limitation is strongest in aquatic ecosystems (because light and water isn't) governed by same principles as terrestrial ecosystems radically different environmental controls streams have been treated as "sewers of terrestrial ecosystems" yet stream ecosystems have their own characteristics generated by the interaction of biota with the physical and chemical properties of the system unlike terrestrial ecosystems, nutrients "spiral" rather than cycle. The more limiting the nutrient, the tighter the spiral. Detritus/heterotrophs <---> autotrophs.

The right answer is Eutrophication.

Eutrophication occurs mainly in ecosystems with slowly changing waters, especially in deep lakes.

In the depths of the lake, where dead algae are deposited, the aerobic bacteria that feed on them proliferate in turn, consuming more and more oxygen. However, in the absence of sufficient water circulation, which is often the case in a deep lake, the lake bottom is poorly oxygenated and the bacteria eventually deplete the oxygen in the deep water layers. They can no longer degrade all the dead organic matter and it accumulates in the sediments. The lake is said to be aging. Such a situation, when it occurs, worsens when it is hot because the solubility of oxygen in water (like that of all gases) decreases as the temperature increases.

Breathing into and out of a paper bag for a long period of time will lead to?

Ilya [14]

Breathing into and out of a paper bag for a long period of time will lead to respiratory acidosis.

<h3>What is respiratory acidosis?</h3>

When the lungs are unable to expel all of the carbon dioxide the body produces, a condition known as respiratory acidosis develops.
Body fluids, particularly the blood, become too acidic as a result.
The main causes of respiratory acidosis are inadequate ventilation and carbon dioxide buildup.
The main issue is an increase in arterial carbon dioxide partial pressure (pCO2) and a decline in the arterial bicarbonate to arterial pCO2 ratio, which causes a drop in blood pH.
When there is acute respiratory acidosis, the body initially tries to make up for it.
If the acidosis lasts more than 12 hours, a reaction known as metabolic compensation2 takes place.
By increasing the release of hydrogen ions through ammonium, the kidneys will lower the blood's acidity.
Too much carbon dioxide in the body can result in general symptoms including headache, exhaustion, and twitching muscles.
Frequently, it goes away fast on its own.
But in cases of severe hypercapnia, the body is unable to return to a stable CO2 level, and the symptoms are more severe.
