Food Web Project

Food Web Project


Directions:
Create a food web for an ecosystem that is nearby. For example a
forest, stream, backyard, saltmarsh, or beach. You are encourage 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.

Vocabulary to keep in mind:
organism
ecosystem
decomposer
food web
producer
consumer
trophic level

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.
  • 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 notmlike 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.
