Cause: Excess phosphorous and nitrogen from human activities; Effect: Algae multiply, block sunlight, and reduce dissolved oxygen harming the food web.

Explanation: Excess nutrients (eutrophication) drive HABs, causing dense algal growth that shades plants and, when decomposed, depletes dissolved oxygen.
