Nutrient Pollution Lesson PowerPoint, Nitrogen, Phosphorus, Eutrophication,

• Which one is Olgiotrophic and which is
Eutrophic?

• What happens in your fish tank if you don’t
clean it after a long time?

 Area of focus: Nutrients and Aquatic
Systems.

• Phosphorus Cycle and Nutrient Pollution
Available Sheet

• Experiment from two weeks ago.
– Please set up three containers with pond or
stream water.
– Have one be control with just water, and then
have the next three have increasing amounts
of nutrients / fertilizer.
– Label each one and place near light source.
Control Low Medium High

– Please sketch what the four containers look
like now.
– What does fertilizer do to an aquatic system?

– Please sketch what the four containers look
like now.

• What does fertilizer do to an aquatic
system?

• What does fertilizer do to an aquatic
system?
• Answer: The nitrogen and phosphorus
caused an increase in plant growth in the
containers over time.

• This bloom occurs from excess nutrients
and sunlight.
– Nutrients include Nitrogen and Phosphorus.

Draw three Lakes – Add the appropriate
colors and vegetation to each box.

• Oligotrophic
– Describes a lake or river with low productivity.

• Mesotrophic
– Production is considered moderate.

• Eutrophic
• Having concentrations of nutrients optimal or
for plant or animal growth. It is used to
describe nutrient or soil solutions.

• Eutrophication.

 Please draw the following
 Half of a page to a full page.
Don’t color yet

“Darn you extra
phosphorus and
nitrogen” “Darn
you.”

• How does excess nitrogen and phosphorus enter
an aquatic system?
– What type of effects can it have if added in excess?

 Eutrophication.

Aquatic plants use Phosphorus and
Nitrogen and grow out of control.

“This algae bloom is
gross!” “Get me out
of here!”

Plants then overpopulate and die.

Bacteria break down dead plants and
use oxygen in water (respiration).

Bacteria break down dead plants and
use oxygen in water (respiration).
C6H12O6 + 6O2 = Released energy + 6CO2 + 6H2O.

No oxygen left for fish / other aquatic
life and they die.

• Which side was given phosphorus in this
water quality study?

• Answer! No nutrients Nutrients (N, P)

• Activity 1-10 – Olgiotrophic, Mesotrophic,
or Eutrophic or Eutrophication

• Answers 1-10 – Olgiotrophic, Mesotrophic,
or Eutrophic or Eutrophication

• Bonus! Name the movie. Happy Gilmore
“Hey Happy.”
“Let me tell you
about nutrient
pollution.”

• You can now complete these questions on
your bundled homework.

• Try and be the first to identify the image beneath
the squares.
– Raise you hand if you think you know. You only get
one guess.

• Try Again! Be the first to identify the image
beneath the squares.

one guess.
