Food Web Project
LS2 7b Developing a model for a food web of local aquatic and local terrestrial
environments.
Create two food webs.
The first food web should be of a local aquatic ecosystem (Narragansett Bay) and the second
food web should be of a local terrestrial ecosystem (Deciduous Forest of Rhode Island). Each
food web is titled as such.
Each slide should have a title. Example: Narragansett Bay Food Web
Each food web should include 15 organisms and the sun. Each food web should include arrows
that show the flow of energy.
All organisms within the food web should be labeled with the name of the organism and the type
of organism it is. Example: Diatoms (Producer)
Food Webs should include producers, consumers and decomposers.
Each food web should be done one slide. Each organism and the sun should have a picture cut
and paste from the internet to represent it.
Please arrange the pictures so the energy flow arrows are all straight and do not cross over
pictures. The arrows may have a single bend to get around a picture.
Do not cut and paste an entire food web. The following page is a sample of organisms found in
the two food webs. You may conduct your own research and use organisms not found on the
following page.

Food Webs are accurate. The organisms consume each
50
other and arrows point in the right direction. Labels are
correct (2 points off per error.)
Slides are neat and attractive. The pictures are the
20
same size or proportional. Labels are spelled correctly.
(Points deducted for proportion of discrepancy.)
Directions are followed. (Points deducted for
