Question

Define eutrophication;what are the ill effects of eutrophication

Answer 1

Eutrophication occurs when an aquatic system has an overabundance of nutrients. ... Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it.

Answer 2

Answer:

It is referred to the natural ageing process of a lake as a result of nutrient enrichment caused by the overflow of nutrients such as fertilizers, animal wastes and sewage from land leading to an increased fertility of the lake. Consequently, there is a huge increase in the primary productivity of the ecosystem bringing about an increased growth of algae, hence in algal blooms. After sometime, the decomposition of these algae reduces oxygen supply, resulting in the death of aquatic animal life.
