Objectives: I CAN. . . .. 1-I can classify
organisms as producers, consumers, scavengers,
or decomposers according to their role in a food
chain or web
Classifying Organisms
Its all about where you get your
energy!
Thinks about it.

Where do you get your energy?
An organism is …..



Any independent
living thing
Can be as small as a
single celled bacteria
Or as large as a
whale!
The three categories of the food
chain are…..
1)
2)
3)
Producers
Consumers
Decomposers
They are all depend on each other.
Producers AreProducers get their
food and energy
from the sun.
 Classified as
autotrophs because
they can make their
own food.
 Example plants.


They make their food
through a process called
photosynthesis.
Consumers
Consumers need to
consume/eat their
food to get energy.
 Classified as
heterotrophs.
 Cannot make their
own food.

Types of consumers are

There are THREE
types of Consumers
 Carnivores
 Herbivores
 Omnivores.

Its still all how
organisms obtain
energy through what
they eat.
Carnivores only eat meat and are
known as secondary consumers.
Herbivores eat only plants and are
known as primary consumers.
Omnivores eat both meat (animals) and plants.
They are known as opportunistic feeders.
Stop…Review…Check…
Turn to your partner and tell them the meaning of each
word. Also give two examples of each.

Carnivore:

Herbivore:

Omnivore:
Decomposers
Decomposers break
down dead things
and through a
chemical reaction,
turn them back into
dirt, or soil.
 Examples:

 Mushrooms
 Worms
 Bugs
What would the world look like
without decomposers (bacteria and
fungi?
Scavengers
an animal that feeds on carrion, dead plant
material, or refuse.
 They are different from decomposers in
that they eat dead organisms and do not
break them down through a chemical
reaction.

How they relate
