Eutrophication and Acid Rain as Nutrient-Cycle Disruptions

State

Eutrophication is nutrient runoff, per Bio 3663, fueling algal blooms whose decomposition depletes dissolved oxygen; acid rain is acidified precipitation disrupting soil and water nutrient chemistry.

Show

Fertilizer runoff into a lake triggers a bloom whose die-off and decomposition consumes the oxygen fish need.

Watch for

Eutrophication kills aquatic life through oxygen depletion after the bloom decomposes, not through algae itself being toxic.
