Eutrophication

• An organism used to monitor the health of an ecosystem.

Dissolved oxygen

• A measure of how clear water is
  
• A fertilizer containing phosphorus compounds
  
• amount of oxygen that is present in the water
  

Which BEST determines the health of a lake used as a source of freshwater? 

• its depth and width
• its temperature and pH
• its location and depth
• its temperature and depth

If a body of water has high turbidity levels, what can MOST LIKELY be concluded? 

• It has a low pH
• It is unsafe to drink 
• It is too hot to drink
• It contains a lot of chemicals 

If a large amount of fertilizer enters a lake, which will most likely happen?
