Eutrophication and Acid Rain as Nutrient-Cycle Disruptions

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

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.
