Eutrophication is the loss of oxygen in a body of water (e.g. pond or lake). This is usually due to algal bloom caused by artificial fertilisers and other chemicals being washed into the water by rain.The 5 stages:1.Chemicals/ artificial fertilisers: Chemicals and artificial fertilisers used on the land (e.g. for farms/crops) are washed into a ...

Leaching from the excessive use of fertilisers causes a nutrient build up in neighbouring rivers or lakes. As a result of the increased nutrients plants within th...

Conveniently, there are roughly 6 main stages in the process of eutrophication, so if you can memorise each one, step by step, you are sure to scoring full marks!...

Eutrophication is where a surplus of nutrients in a lake or pond leads to an overgrowth of plant life, causing a shift in the biodiversity. There are 5 steps to this process: Step 1: The use of fertilisers on farmland is washed into lakes and rivers.

These dead plants are then broken down by bacteria, which uses up even further oxygen. Thus, the fish in the water now have so little oxygen that they die. Eutrophication, therefore, is a process which harms the ecosystem, and demonstrates one of the many negative impacts of fertilisers.

Eutrophication occurs when nitrate fertilisers are carried by ground water into lakes and ponds. The fertliser encourages algal growth in the water, which in turn blocks out sunlight.

Eutrophication (also called algal bloom) is a massive growth of green plants in lakes and rivers, caused by the use of fertilisers in industry, washed off the land by rain.The fertilisers cause the green plants to grow, and as they do they cover the surface of the lake, preventing sunlight from reaching plants so they can no longer photosynthesise.

Eutrophication occurs when mineral ions from the soil such as nitrates are leached (washed away by the rain) and they run into rivers, lakes and ponds. This increase in nutrients into the water causes an increase in growth of algae called an algal bloom which covers the surface of pond and blocks sunlight from reaching the plants in the water.

Eutrophication occurs when excess nitrates from fertilisers seep into the stream. The nitrates cause algal bloom on the surface of the water. As a result, sunlight is blocked from reaching the plants underwater so they cannot photosynthesise. Without photosynthesis, no oxygen is produced from the plants.

1. Fertilisers are washed into waterways by rain or irrigation. 2. The increased availability of nutrients causes aquatic plant life to grow rapidly. 3. An alga...
