PRODUCERS,
CONSUMERS, and
DECOMPOSERS
Objective:
Can I identify producers,
consumers, scavengers, and
decomposers in a food chain or
food web?
ALL LIVING THINGS
NEED
Energy
TO SURVIVE
SUNLIGHT
is the source of energy for
almost all living things
On a Post It note:
• Write:
P=
C=
D=
Write examples of plants/animals that are
producers, consumers, and decomposers.
1. Producers
Organisms that use sunlight
directly to make food
• They do this by a process called
PHOTOSYNTHESIS
PRODUCER EXAMPLES:
Grass, Plants,
Trees Corn
Reality Check
• Can I identify producers, consumers,
scavengers, and decomposers in a
food chain or food web?
2. Consumers
Organisms that eat
producers or other
organisms for energy!
There are 4 Types of
Consumers:
Herbivores
Carnivores
Omnivores
Scavenger
A. Herbivores
Consumer that
eats plants
B. Carnivores
Consumer that
eats animals
(meat).
C. Omnivores
• A consumer
that eats both
plants and
animals.
Herbivore
Koala
Deer
Carnivore
Shark
Raccoon
Fox
Snake
Rabbit
Horse
Rhino
Omnivore
Tiger
Hedgehog
Chicken
Bear
D. Scavenger
Feeds on the
bodies of
dead animals.
Weird Science
• Having survived for 300 million years, the common
cockroach may be the most successful and welladapted scavenger of all time. Cockroaches
scavenged dinosaur leftovers long before they
survived on the crumbs and kitchen scraps of
humans. Dead skin and fingernails are a real treat
for them; leftover food is a delicacy. If these tasty
morsels aren’t available, cockroaches can survive
on such unlikely food sources as shoe polish, paint,
and soap.
Reality Check
• Can I identify producers, consumers,
scavengers, and decomposers in a
food chain or food web?
3.Decomposers
Organisms that get energy by breaking
down the remains of dead organisms.
Known as NATURE’S
RECYCLERS and adds
nutrients to the soil!
Decomposer Examples:
Bacteria and Fungi
Ex. Of producer, consumer,
decomposer, and scavenger

Predator:
Eat Prey
Example:
A Lion
eats a rabbit.
The lion is the
predator.
Prey:
The organism that is eaten
Example:
The Lion (predator)
eats the Rabbit (prey).
The PREY is
the Rabbit
