Give a reason for the following:

Run off from fields leads to death in adjacent waterbodies

Answer 1

1. Chemical fertilizers and pesticides used in agriculture cause runoff from fields to pollute nearby water bodies, resulting in death.
2. When these compounds enter water bodies, they can change the pH, cover the surface, and lower dissolved oxygen levels.
3. Toxins can injure aquatic creatures, leading to biomagnification and accumulation.
