How does eutrophication affect other organisms in the water?

• The algae provides food to other organisms

• Oxygen is used up as the algae decomposes, reducing the available oxygen

Run-off (pollution)= increased nitrogen in water

Increased nitrogen in water= rapid algae growth (eutrophication)

Eutrophication= less oxygen available to aquatic animals
