Students will research what food is eaten by the following
organisms: penguins leopard seals, krill, elephant seals,
petrels, albatross, fur seals, squid, insects and grass.
Students will make a food web using the data they have
B. Analyze plant and animal structures and functions
needed for survival and describe the flow of energy through
a system that all organisms use to survive.

02. Explain how almost all kinds
of animals’ food
can be traced back to plants.

03. Trace the organization of simple food chains and food
webs (e.g., producers, herbivores, carnivores, omnivores
Students will discuss what life forms are present in
Break students into groups and have each group go online
or go to the library to find out what each of the following
Penguins (eats krill, squid and small fish)
Albatross (eats krill, squid and small fish)
Petrel — small to medium sea birds
(eats plankton, krill, squid and small fish)
Fur seals (eats krill, fish, squid and sometimes
Elephant seals (eats squid —
75% of its food — and fish)
Leopard seals (eats squid, fish, krill and penguins)
Sperm whales (eats squid, fish, birds, seals and
Blue whales (eats krill and fish)
Krill (eats plankton, krill eggs and krill larvae)
Pass out the student activity
sheet so that they can fill in what each organism
- Students will then get with a partner and construct
a food web using the information that they gathered.
If you wish, you can give the students copies of the
pictures to use in their web.
