to produce their own
food
What do
zooplankton eat?
Other small

phytoplankton
What are two terms
that could be used to
describe the role of
phytoplankton in a
food web?
Producers and
autotrophs
What are two terms
that could be used to
describe the role of
zooplankton in a food
web?
Consumer and
heterotroph
If zooplankton eat
phytoplankton, they
would be considered a
_____-order
consumer.
First
(First order
consumers eat

word tertiary
mean?
Third
(Tertiary consumer
= third-level
consumer)
Which direction do
the arrows on a
food web point?
From the organism
being consumed to
the one consuming it
(Shows energy flow)
If an organism is both
a secondary and a
tertiary consumers, it
eats ___________ and
__________

consumers and
secondary
consumers
Which level of
consumers are

As you move up in a
food web, does the
amount of available
energy increase or
decrease?
Decrease
If 2500 calories are
available at the level of
producers, how many
calories would be
available at the level of
primary consumers?
250
(2500)*(0.10) = 250

transferred from one
trophic level to the next,
what happens to the other

Hint: think cane toads!
Biological Control
How can
eutrophication affect
the producers in a
food web?
