Name _______________________________Period __________
Assignment: Create a SMALL poster that shows a Minnesota Food Web and explains the relationship between the organisms.
Then, research one invasive species that has entered the food web. Draw the invasive species in the correct placement on the
food web and write about its impact. Poster is to be no larger than 24 X 24 inches.
This box is for your teacher to assess
your work.
1. Complete the chart of MN organisms. ***
2. Use the MN organisms to draw a food web. Be sure to:
Food Web
______ title above the food web
______ organisms organized correctly
______ label each level
______ correct shape
______ arrows correct
______ drawn and colored neatly
_____* Use arrows to show all energy flow relationships.
_____*Label each trophic level.
_____*Draw your web with a trapezoid shape.
3. Write 2 paragraphs that explain:
_____ *Where food production starts.
Paragraphs
______ 3 to 5 sentences in each
paragraph.
______ Producer paragraph
______ interactions paragraph
______ uses specific vocabulary from
the provided list (feel free to use
more!)
_____ *Explain why the producer level is so large and the
tertiary consumer level is so small.
_____ *Explains some of the abiotic and biotic factors in a
MN Ecosystem.
_____ *Write 2 examples of organisms interacting with
biotic factors.
_____ *Write 2 examples of organisms interacting with
abiotic factors.
Organisms
______ used 13 organisms
______ number of extra organisms
4. Write 2 paragraphs that explain:
Total score ___________
______ * Where geographically the invasive species is a native species.
______ *How and when the invasive species was introduced to this food web.
______ *Consequences of the invasion of the invasive species.
______ *Explain the actions and results humans have taken in removing the species.
***For this project, there are 20 organisms possible to use in your food web. 13 organisms are required to use in your food web. To
score an “8”, you need to include all 20 organisms.
