We used bioindicators to measure the quality of water.  What is a bioindicator?

• any living creature
• eutrophication
• An organism sensitive to its environment
• a turbidity tube

What is the healthiest combination listed?

• low pH, high nitrates, neutral temperature
• low temperature, neutral pH and low nitrates
• as many nitrates as possible, low temp and low pH
• high temp, high nitrates and high pH

NGSS.MS-LS1-5

High turbidity means.....

• very clear water

• neutral pH

• very cloudy or murky water

• high nitrates

how does increasing nitrates impact stream health

• leads to excess algae

• leads to increased oxygen

• leads to increased water clarity

What is the end result of eutrophication?

• More algae
• decreased oxygen and fish kills
• less turbidity
• a new pond

If water temperature goes UP, what happens to the level of Dissolved oxygen?

• It goes up
• It goes down
