How is it possible to include that eutrophication of bodies of water has occurred?
A - By testing for levels of acidity in water
B - By having a vibrant, productive aquatic ecosystems
C - By having greater species diversity in the water
D - By having massive algae blooms
Answer: D - By having massive algae blooms
EUTROPHICATION is the ecological process that occurs when excess nutrients are added to a body of water. It can occur naturally over a long period of time, allowing the organisms to get use to it, but if it is caused unnaturally by humans it can hurt the environment.
