Nutrients like nitrate and other ions enter the water from an exterior source; plants grow, especially at the surface where there is more light; light is blocked for underwater plants, and they die; since surface plants have their stomata in the air, oxygen escapes the water into the air and is not replaced because the underwater plants are dead; decomposers inside the water also consume the dead plants, which requires more oxygen; eventually, there is not enough oxygen for life, and the ecosystem dies.
Næringsstoffer som nitrat og andre ioner kommer ind i vandet fra en ydre kilde; planter vokser, især ved overfladen, hvor der er mere lys; lyset blokeres for undervandsplanter, og de dør; da overfladeplanter har deres spalteåbninger i luften, undslipper ilt vandet ud i luften og erstattes ikke, fordi undervandsplanterne er døde; nedbrydere inde i vandet forbruger også de døde planter, hvilket kræver mere ilt; til sidst er der ikke nok ilt til liv, og økosystemet dør.
