Eutrophication

• Eutrophication


  . When fertilisers leach through soil from farms and run off into bodies of water they over nourish the water forming algae blooms, this is called Eutrophication

  . The algae blooms block out sunlight preventing underwater plants from photosynthesising

  . The plants all die out and the fish die from starvation

  . The saprobionts/decomposers use the remaining oxygen to decompose the fish via aerobic respiration

  . This depletes the oxygen levels in the water and increases the carbon dioxide levels

  . This causes a dead body of water
