Create a Food Web
Due: May 4-5, 2011
1. Pick a biome from the container
2. You will develop a food web using that biome.
3. You must have a minimum of 10 organisms! They must be members of the
biome/habitat to count towards the 10. Example: You pick the desert biome, but
a Polar bear is on your Food Web. The polar bear would result in minus 5
4. You must have at least 2 producers from that habitat and at least 2 top-level
consumers.

CARNIVORES in RED, and OMNIVORES in YELLOW!

Points
Deducted
Number of organisms – remember the project must have a minimum of 10
organisms with 2 producers and 2 top-level consumers. Organisms that are
not part of the Biome/Habitat selected will not count towards you 10
minimum. (-3 for each missing)
Neatness – arrows lead away from the prey to the predator and can be
easily followed. The names of your organisms are clear and neat! (-1 for
each arrow pointing in the wrong direction, messy names, or messy
arrows)
Color – the names are colored and following the color code from above! (2 for each name not in color or organism not following color code)
