Answer 3 – 30 Pathogens

Question 3 - 40 The difference between permeable and impermeable layers?

Answer 3 – 40 Permeable= contain spaces/pores through which water can pass Impermeable= the layer that doesn’t allow water to pass through it

Question 5 - 10 Too much of what nutrient leads to eutrophication?

Answer 5 – 10 Phosphorous

Question 5 - 20 A sudden explosion of algal growth caused by excess nutrients

Answer 5 – 20 Algal bloom

Question 5 - 30 How does eutrophication harm ecosystems?

Answer 5 – 30 Leads to less dissolved oxygen in the water (due to decaying organisms) and blocks sunlight (no photosynthesis!)

Question 5 - 40 What is the difference between eutrophication and cultural eutrophication?

Answer 5 – 40 Eutrophication occurs naturally, whereas cultural eutrophication is man-made.

Question 5 - 50 Using the concept of watersheds, explain how over fertilization on a farm in Minnesota could affect fish in the Gulf of Mexico

Answer 5 – 50 Nutrients from fertilizer build up in water. Algae and aquatic plant growth increases. A farm in Minnesota is on the Mississippi River’s watershed. Any fertilizer, will runoff into the Mississippi River which empties into the Gulf of Mexico, leading to eutrophication. Organisms/Fish die. Decomposition requires oxygen. Dissolved oxygen levels decrease.
