Organisms need
food
in order to
survive
Some
organisms
make their own food, while others eat other organisms for food
We can describe the
relationships
between
organisms
based on the food they eat
The
Sun
is the main source of energy for all plants, which can
trap light
from the Sun directly
All other organisms get
energy
from the
Sun
indirectly
Plants trap light from the
Sun
to make food during
photosynthesis
Energy from the food made by
plants
may be used by the
plants
or stored in parts of the plants
The
rabbit
is a plant-eater, it gets
energy
from the plants it eats
The
bear
is a plant-and-animal eater, it gets
energy
from the plants and other animals it eats
The
falcon
is an animal-eater, it gets
energy
from the other animals it eats
Producers
Plants that can make their own food using
chlorophyll
and
sunlight
Consumers
Organisms that cannot make their own food and eat
plants
or other
animals
If there were
no
producers, there would be
no
food for consumers
Predators
Animals that
hunt
and
kill
other animals for food
Prey
Animals that are
killed
and
eaten
by predators
Predators help to control the number of
prey
in a community
Food chain
A series of
organisms
where each
consumes
the one below it
Food chains always begin with a
producer
Energy
is transferred from one
organism
to another in food chains and food webs
Food web
Interconnected
food chains
in a community
Organisms in a community
depend
on one another
When the population of one organism
increases
or
decreases
The populations of other organisms in the community are
affected
