What starts the process of eutrophication?

Excess nutrients

Excess carbon dioxide

Excess fish

Excess oxygen

1

Because of the bacteria in the water, what is used up when decomposition occurs?

Nitrogen gas

Carbon dioxide

Oxygen

Argon

1

What happens when all of the oxygen is used up in the water?

A dead zone is created

A live zone is created

Plants growth increases due to high levels of CO₂

An algal bloom is created

Describe how we can prevent eutrophication.

Explain the DO lab results.

Background:

Some of today’s more pressing environmental problems can be quite complicated and difficult for the average person to understand. Failure to accurately understand them may impact both how and when the problem gets attention. TV commercials, billboards, pamphlets, radio ads, and flyers have all proven helpful in this regard (EDUCATING THE PUBLIC!!!)

Your Task:

Create a comic strip educating your audience about eutrophication.

Identify its main causes, its consequences and make some recommendations for what can be done to solve the problem.

Some thoughts:

A. You may target a young audience or an older audience.

B. You are not graded upon your art skills, just your accuracy, thoroughness, and creativity.

C. The comic will be six panels to cover the subject and its possible resolution.

D. You may use many different sources for ideas and/or background information.

E. You must mention or illustrate: nitrogen/nitrates, phosphorous/phosphates, nutrients, eutrophication, phytoplankton, algae, dead zones, DO (dissolved oxygen), and decomposition

The six steps of eutrophication are

1)Addition of eutrophication sources (fertilizers, detergents, wastewater)

2) Runoff into bodies of water

3) Algal bloom from excess nutrients

4) Plants underneath algal bloom die from lack of photosynthesis

5) Algae uses up all nutrients and dies

6) Bacteria decomposes dead aquatic plants, creating a hypoxic zone (lack of O₂) killing aquatic organisms

What is required for eutrophication to occur?

A body of water being enriched by nutrients

A body of water being enriched by sunlight

A body of water being enriched by bacteria

A body of water being enriched by organisms

1

A hypoxic waterway has a lack of

Nutrients

Dissolved carbon dioxide

Dissolved oxygen

Sunlight

1

The opposite of eutrophic is oligotrophic. An oligotrophic waterway has

low nutrients, increasing algae populations, and low dissolved oxygen

high nutrients, no algae populations, and low dissolved oxygen

low nutrients, stable algae populations, and high dissolved oxygen

high nutrients, increasing algae populations, and low dissolved oxygen
