Water Quality Quiz

What happens to the amount of dissolved oxygen when the temp. decreases
dissolved oxygen increases
why would a fish have a higher respiration rate in warmer temp. water
it breathes faster because there is less dissolved oxygen in the water
if water has more carbon dioxide in it, it becomes
more acidic
in photosynthesis, plants use....and produce....
carbon dioxide and oxygen
eutrophication can be caused by
algal blooms due to excess nitrates from fertilizers
if acid rain falls into a pond, what happens to the pH
pH decreases
what is the name of the law that was passed to protect water from having pollutants dumped into it?
clean water act
the deeper the water the....it is
turbidity is a measure of
how clear the water is/clarity of the water is
Living factors to asses water quality
what happens to the pH of a stream after an acidic rainfall
decrease in pH
what happens to the dissolved oxygen levels if plant growth increases
oxygen is being produced
algal bloom eventually leads to...
sediment and debris in water from constrution runoff would most affect which water quaility factor
what is the role of bacteria in the nitrogen cycle
it fixes nitrates
eutrophication=debris=decomp. what would happen to the pH lvls.
pH goes down
Name as many factors you can think of that cause water pollution
pesticides and runoffs and fertilizers and acid rain and air pollution and decomp.
cycle where plants and animals exhange gases
oxygen/carbon dioxide cycle
legislation mandating cleaner surface waters in america
clean water act
relationship between temperature and dissolved oxygen
when temp. increase then oxygen decrease and if temp. decrease then oxygen increase
bioindicatiors used to quickly asses stream health because they are sensitive to pollution and can't easily escape it are what
macro invertebrates
what is the relationship between DO and the diversity of living things in water
more do, more diversity
chemical process when plants create oxygen and glucose
chemical process when it breaks down glucose using oxygen
glucose is what to fish
suppose nitrate level rose significantly for several weeks
plants and animals would eventually die and then soon everything would follow
removal of waste
if the water has group A macro inveratbrates is it healthy or polluted
extremely healthy
if the water has group B and C is it healthy or polluted
some polluted
if the water has only group C
it is extremely polluted
singular cell organism , not a plant
clean water act
help protects our nations by preventing them from being polluted since year 1972
specific species are more or less tolerant of ....
if temp. increases what happens to the photosynthesis
photosynthesis increases
increase of photosynthesis affects the pH,how?
pH level would increase because carbon dioxide in oxygen gets used removing carbon dioxide from the oxygen and remove acid from the oxygen
why is algal bloom a concern to water quality
there would be a lack of sunlight and all the fish would die which is called eutrophication
describe oxygen and carbon dioxide cycle
plants take in carbon dioxide and create oxygen and animals and humans use respiration to take in oxygen and create carbon dioxide and then cycle starts over again
