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 thateats animals
(meat).
C. Omnivores
• A consumer
that eats both
plants and animals.
Herbivore Carnivore Omnivore
Shark
Rhino
Hedgehog
Bear
KoalaRaccoon
SnakeRabbit
ChickenTiger
Fox
Horse
Deer
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 well-adapted 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.DecomposersOrganisms 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 Lioneats 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
