Eutrophication is caused by leached mineral ions stimulating algal growth, blocking light for plants below; bacteria decomposing dead matter reduce oxygen, leading to the death of aquatic organisms.
Eutrofizarea este cauzată de ions minerali leșiați care stimulează creșterea algelor, blocând lumina pentru plantele de dedesubt; bacteriile care descompun materia moartă reduc oxigenul, ducând la moartea organismelor acvatice.
| Front | eutrophication |
|---|---|
| Back | mineral ions leached from fertilizer fields stimulate the rapid growth of algae in ponds and rivers large amounts of algae block light from reaching the plants below eventually plants die because they're unable to photosynthesise enough bacteria feed on dead plant matter and so the oxygen concentration decreases fish and aquatic organisms die because there isn't enough dissolved oxygen |
