The process of nutrient enrichment of water bodies is called as

Options

A. Euthrophication
B. Stratification
C. Atrophication
D. Biomagnification

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the process of nutrient enrichment in water bodies.

2. **Reviewing the Options**:
- **Option 1: Eutrophication** - This term refers to the process where water bodies become enriched with nutrients, particularly phosphorous and nitrates, leading to excessive growth of algae.
- **Option 2: Stratification** - This term refers to the layering of vegetation or different strata in an ecosystem, which is not related to nutrient enrichment.
- **Option 3: Atrophication** - This term is not commonly used in environmental science and refers to the wasting of cell tissues, making it irrelevant to the question.
- **Option 4: Biomagnification** - This term describes the increasing concentration of toxic substances in organisms at each trophic level of a food chain, which is unrelated to nutrient enrichment.

3. **Identifying the Correct Answer**: Based on the definitions provided, the correct answer is **Option 1: Eutrophication**. This is the process that specifically describes the nutrient enrichment of water bodies.

4. **Conclusion**: Therefore, the process of nutrient enrichment of water bodies is called **Eutrophication**.
