A model that shows how
energy
passes from
organism
to
organism
is called a
food
chain.
Organisms at the very
start
of a food chain that can create
glucose
using
photosynthesis
are known as
producers.
Which two of the following groups of organisms are producers?
algae
plants
Producers
are
organism
that
create
their own
food
using
energy
from the
sun.
Which resource do plants not compete for?
Food
What do primary consumers feed on?
Producers
Tertiary
consumers are
organisms
that eat
secondary
consumers.
As
energy
passes
along a
food
chain
, most of the
energy
is
lost
Which is the secondary consumer in the following food chain?
tree → caterpillar → shrew → owl
shrew
What is a predator?
An
animal
that
hunts
and
kills
other
animals
for
food
An
organism
that is
killed
and
eaten
by a
predator
is known as
prey.
The diagram above shows the predator-prey cycle between snakes and rabbits.
At time X, the number of predators is
increasing
because there is a lot of
prey.
At time Y, the number of predators is
decreasing
because there is less
prey.
At time Z, the number of prey is
decreasing
because there are now more
predators.
