Algae are the major producers of any aquatic ecosystem. Run-off of nutrients such as animal wastes, fertilisers (N and P) and sewage from land leads to an increase in the fertility of the lake. It causes a tremendous increase in the primary productivity of the water body leading to increased growth of algae, resulting into algal bloom.
Later, the decomposition of these algae depletes the supply of oxygen, leading to the death of other aquatic animal life. This is called eutrophication.
Eichhornia crassipes (water hyacinth) also called Terror of Bengal can grow in such eutrophic lake.
How does on algal bloom cause eutrophication of a water body? Name the weed that can grow in such a eutrophic lake.
