Answer: Eutrophication
Explanation:
Eutrophication occurs when the amount of nutrients and minerals deposited in water bodies such as rivers, lake etc is at an increased rate such that the number of aquatic organisms multiplies leading to reduction in oxygen present in the water. Examples of human activities that cause eutrophication are
- uncontrolled use of fertilizer
- application of chemical such as pesticides, herbicides on farms, as they could be washed by rain into nearby lakes
