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
