Food Web Design
You are being interviewed by a Fortune 500 company to serve as an
environmental consultant. Given your vast knowledge of ecosystems,
organisms’ interactions, feeding relationships, and so on, the company
requests that you create a food web of a particular habitat area that
would be included with an environmental impact report to show off your
expertise. So, choose any habitat area such as the intertidal zone,
tropical rainforest, desert, deciduous forest, coniferous forest,
tundra, or any other habitat of your choosing and generate a food web
for that area.
The food web must include sketches and common names of each of the
following:
1. Ultimate source of energy that starts it all for most food
webs
2. 7 Producers
3. 5 First order / primary consumers
4. 4 Second order/ secondary consumers
5. 2 Third order/ tertiary consumers
6. 2 Decomposers
Make sure to include:
Answer the following questions on the back or an attached piece
of paper.
1. Explain to the company why food chains (and in essence food webs) don’t
th
th
go on forever. Meaning, why aren’t there 7 , 8 order consumers?
2. Explain to the company why a food web is more stable than a food
chain.
3. Describe the possible ramifications of the release of a toxin by the
company into the ground water that supplies the organisms in that area.
Hint: think about the process of biomagnifications.
4. Say the company’s project will destroy the habitat of one of the 2
level consumers – Explain what the effects of this may have on the
ecosystem.
