Agricultural Runoff and Coral Reefs
Coral reefs located near agricultural areas often exhibit higher rates of algal overgrowth compared to more isolated reefs. Which of the following sequences of events best explains this phenomenon?
A
Irrigation withdrawal → increased salinity → coral stress → algal invasion
B
Fertilizer runoff → eutrophication → algal bloom → coral shading
C
Pesticide runoff → coral poisoning → predator decline → algal growth
D
Soil erosion → increased water clarity → UV damage → coral death
