Question

The process of nutrients enrichment is termed as :
A. Limiting Nutrient
B. Eutrophication
C. Enrichment
D. Schistosomiasis

Answer 1

Hint: Nutrient enrichment is the process in which a water body becomes overly enriched with nutrients, leading to plentiful growth of simple plant life. The excessive growth (or bloom) of algae and plankton in a water body are indicators of this process.

Complete step by step solution:
Nutrient enrichment is called Eutrophication. It drives excess primary productivity in waterways. It can be either natural or caused by human impact.
Eutrophication is a very slow process in which a river, lake or another shallow water source deteriorates in the marsh and later on dies. Nutritive pollution is one of the important factors of eutrophication due to which aquatic plant and animal life of this water is destroyed.
Excessive richness of nutrients in a lake or other body of water, frequently due to run-off from the land, which causes a dense growth of plant life, is known as eutrophication.
The process of eutrophication can be categorized into two types based on its root cause. Both these types are as follows
\[1.\] Anthropogenic Eutrophication is caused by human activity. Agricultural farms, golf courses, lawns, etc. are supplied with nutrients by humans in the form of fertilizers. These fertilizers are washed away by rains and eventually find their way such as lakes and rivers.
\[2.\] Natural Eutrophication refers to the excessive enrichment of water bodies via natural events.
For example, the nutrients from the land can be washed away in a flood and deposited into a lake or a river.

So the option(B) is correct

Note:
Eutrophic waters can eventually become “dead zones” that are incapable of supporting life. In order to stop this, by restoring the shellfish that are mussels and oyster where they remove nitrogen from the water bodies and also filter the suspended solids.
