Question

Plenty of algal bloom is observed in pond in your locality.

Answer 1

The term 'Eutrophication' means nourished or enriched. In context with the environment, the Eutrophication can be defined as the addition of artificial or non-artificial substances such as nitrates and phosphate, through fertilizers or sewage, to a freshwater system. It leads to an increase in the primary productivity of the water body or 'bloom' of phytoplankton. So, when there is an excess growth of the algae or blooms in the locality the reason is the excess pollution of water.
