==Key Stage 3==
===Meaning===
'''Eutrophication''' is a process which kills [[animal]]s in lakes and rivers due to pollution.
===About Eutrophication===
#Fertilisers are washed from the soil into rivers and lakes by the rain.
#The fertilisers cause [[algae]] to grow uncontrollably.
#The [[algae]] cover entire surface of the water blocking out all sunlight to the [[plant]]s below.
#Most of the [[algae]] and the [[plant]]s die due to lack of sunlight.
#The water no longer holds as much [[dissolve]]d [[Oxygen]] so the [[animal]]s die.
