Key Stage 3
Meaning
Eutrophication is a process which kills animals 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 plants below.
- Most of the algae and the plants die due to lack of sunlight.
- The water no longer holds as much dissolved Oxygen so the animals die.
