| A | B |
| Nutrient Pollution | excess amounts of phosphorus and nitrogen in the water lead to the process of eutrophication |
| Harmful Algal Blooms | excessive algae growth due to nutrient pollution |
| Hypoxia | occurs when there is substantial DECREASE in the amount of dissolved oxygen in the water leading to mass fish kills |
| Eutrophication | a process that occurs when a body of water becomes enriched with nutrients, leading to an overgrowth of algae and other plant life |
| Where does all the nitrogen and phosphorus come from? | runoff from farms / farm animals |
| Order of Eutrophication Process | Excess Nutrients>Runoff into waterways>harmful algae blooms cut off light> organisms die without sun> decomposers use all the oxygen to breakdown dead organisms > low oxygen leads to hypoxia (dead zones) |
| Plants in the water need ___________ for photosynthesis and release _______ into the water | sunlight / oxygen |
| How can we decrease nutrient pollution? | using more sustainable fertilizers |
| Decomposers | bacteria and fungi break down dead nutrients for energy (taking in oxygen for cellular respiration) |
| Algae | single celled autotrouph |
