Food Web Group Mini-Project
Objective: Create and analyze food webs for various biomes.
Requirements:
1. Creation of one food web for a given biome. Use the cards provided. You will submit a picture of
this food web.
o Use your phones to research what each organism eats. Use this information to create a food
web.
o Draw the arrows to show the flow of energy for your food web on your lab tables using the
chalk provided.
o Take a picture of your completed food web. You will send either print this picture out to
turn in with this worksheet or email the picture to me: bluancing@methacton.org
2. Answer the Identification & Analysis questions as a group.
3. Complete the peer review sheet.

Identification Questions
Biome:___________________________________________________
A. How many producers are present in your biome? _____________________________
B. List your producers (at least 4): ________________________________________________________________________
_____________________________________________________________________________________________________________
C. How many primary consumers are present in your biome? ____________________________
D. List your primary consumers (at least 4): ______________________________________________________________
______________________________________________________________________________________________________________
E. How many secondary consumers are present in your biome? ____________________________
F. List your secondary consumers (at least 3): ______________________________________________________________
________________________________________________________________________________________________________________
G. How many tertiary consumers are present in your biome? ____________________________
H. List your tertiary consumers (at least 1): ______________________________________________________________
______________________________________________________________________________________________________________
I. Do you have any quaternary consumers? If so, write the name of it (them):
______________________________________________________________________________________________________________
J. List at least 2 animals that could be more than 1 type of consumer (such as primary and tertiary)
and write out the food chains that shows how they are both (do not need to draw the food chains;
just write their commons names with arrows in between).
Animal 1:____________________________________
Food chain a:
Food chain b:
Animal 2: ____________________________________
Food chain a:
Food chain b:
K. Analyze each of these food chains and explain, out of those 2 food chains, which is the most
efficient feeding relationship for that organism. (Hint: this has to do with the 10% rule and how
the food gets to the consumer.) EXPLAIN YOUR ANSWER.

Analysis Questions
1. In the space below, create a trophic level (energy) pyramid for your biome. You will:
a.
b.
c.
d.
Draw in lines to separate each trophic level based on how many levels you have.
On the RIGHT side of the pyramid, label each trophic level.
On the LEFT side, label the Autotrophs & Heterotrophs
Write the names of all organisms into the appropriate trophic level. For organisms who can
occupy more than one, simply choose a trophic level for it. Your choice must make sense for all of
the organisms that interact with it.
e. Write the name of the Biome below the Energy Pyramid.
2. Assume your biome receives 500,000 kilojoules(kj) of energy from the sun (note this does not mean
the producers obtain 500,000). Fill in the chart below by calculating the amount of energy present at each
trophic level.
Trophic Level
Energy Present
Producer
Primary Consumer
Secondary Consumer
Tertiary Consumer
Quaternary Consumer (assume you have one)
3. How many producers are present in your biome? ________________________________________
4. How many tertiary consumers are present in your biome? ________________________________
5. Which (producers or tertiary consumers) are greater in number? ________________________________________
6. Why does this trophic level contain more organisms? Explain using your knowledge of the amount of
energy available at each trophic level.

Food Web Picture
You need to submit your picture of your food web. You can either:
1. Print out your picture and tape/glue it to this page
2. Go to my website, download this page and digitally copy it onto this page. You would then print
this page out or email it to me (bluancing@methacton.org).
