Define the following:
Eutrophication

Explanation

**Step-by-Step Text Solution:**

1. **Definition of Eutrophication**: Eutrophication is the process by which water bodies, such as lakes and rivers, become overly enriched with nutrients, particularly nitrogen and phosphorus.

2. **Nutrient Enrichment**: This nutrient enrichment often results from human activities, such as the use of fertilizers in agriculture. When it rains, these nutrients can wash off the land and enter nearby water bodies.

3. **Growth of Aquatic Life**: The increased nutrient levels lead to a rapid growth of aquatic plants, especially algae. This phenomenon is often referred to as an "algal bloom."
