Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Eutrophication is the naturally occurring ageing process of a water body but it has been accelerated when a water body becomes excessively nutrient and minerals rich due to anthropogenic activities, which induce overly growth of plant and algae e.g., increase of phytoplankton in water body, resulting in oxygen depletion because of bacterial degradation of biomass consumes oxygen. So, the levels of dissolved oxygen are severely reduced. The causal factors are the discharge of sewage and agricultural fertilisers containing nitrate which stimulates disproportionate growth.

Concepts Used:
Water Pollution
- Water pollution means the contamination of water bodies such as seas, lakes, rivers, aquifers, oceans, and groundwater caused majorly due to inhuman activities with industrial and agricultural effluents. It is the change of chemical, biological, or physical properties of water that will result in a destructive consequence for living organisms.
- Portable water is considered safe for human and animal consumption as well as used for drinking, cooking, crop irrigation, washing, etc,. Nowadays, chemicals, bacteria, and other pollutants are also influencing this. It adversely acts on all the living forms, directly or indirectly depending upon the source. The effects of water pollution can be felt for years to come.
Sources of Water Pollution:
The following are the major sources of Water Pollution:
- Domestic Waste
- Urbanization
- Deforestation
- Industrial effluents
- Social and Religious Practices
- Insecticides and pesticides
- Detergents and Fertilizers
