Food Web Project
Create a food web for an ecosystem that is within the State of Maine. For example a forest, field, stream, backyard, saltmarsh, or beach. You are encouraged to choose an ecosystem that you are familiar with. You should organize your food web so that relationships between organisms are demonstrated (like we did in class).
A good way to start:
Brainstorm organisms within an ecosystem (you should have 15-20)
Place the organisms into groups: producer, consumer, decomposer (click to find more).
Vocabulary to keep in mind:
decomposer (click here to learn more)
Checklist of Required Items
Your food web should:
- have 15 - 20 organisms represented in the food web.
- identify the name of each organism (this should be specific, do not just list fish or tree).
- include arrows to indicate the flow of energy (going in the direction that the energy travels)
- have at least 2 of every trophic level represented (decomposer, producer, consumer).
- show many organisms interacting.
- contain a sketch for each organism (computer printed images are OK if you do not like to draw).
- use a ruler to draw straight lines.
- contain color.
- contain a title (example - A Tidal Pool Food Web).
- contain your name and group.
