1
AIMWhat are Producers and Consumers?
Objectives
Explain the term producer and different types
of consumers in an ecosystem
2
AIMWhat are Producers and Consumers?
Vocabulary
Consumer (3 types ), producer, decomposer,
scavenger, omnivore, herbivore, carnivore
3
Why do scientists group things? What is the
advantage to grouping? Our vocabulary list
represents groupings of organisms
4
Examine the next 8 slides How could an ecologist
group these organisms? What do all these
organism do?

What did the last 8 slides have in common? How
could they be grouped? What do plants do? They
produce their own food They are called
producers
14
Do producers only live on land? What do you call
producers that live in water? Where do producers
get their energy in order to make their own food?
15
Examine these next five slides. What do they all
have in common? How could an ecologist group
these animals?

What did those animals eat?
22
These animals eat producers They get their energy
by eating other organisms. We call these animals
consumers. Consumers are organisms which get
their energy by eating other organisms
23
Examine the next five slides How do they compare
with the previous five slides? How do they differ
then the previous five slides?

What was different about the last five
slides? Did they eat plants like the first set of
animals? What were they eating? They were eating

consumers Consumers that eat other consumers are
called secondary consumers. Consumers that
eat other consumers, who ate other consumers are
called tertiary consumers.

Suppose some insects ate the grass. The mouse ate
the insects, and then the snake ate the mouse.
What level consumer would the snake be?
35
Suppose some worms ate the grass. A small bird
ate the worms, and then the falcon ate the small
bird. What level consumer is the falcon?
36
Come up with an example which would make the
polar bear a secondary consumer, and then a
tertiary consumer.
37
Come up with an example which would make the
alligator a secondary consumer, and then a
tertiary consumer.
38
Come up with an example which would make the lion
a secondary consumer, and then a tertiary
consumer.
39
What type of organism is man?

• What type of organism would an ecologist classify
  a duck as?
• Duck eat grasses, insect, small fish.
• Ducks could either be a primary or a secondary
  consumer!

40
Analyze these next four slides. All of these
animals have a particular way of feeding
themselves How would an ecologist classify these
animals?

What did the last 5 slides have in
common? They were organisms that break down the
remains and wastes of other animals and plants
53
They return the dead organisms nutrients back to
the soil and the environment
54
Organisms that break down the remains and wastes
of other animals and plants are
called DECOMPOSERS Examples of which are
bacteria, maggots, certain insects, worms
55
Herbivore
Omnivore
Carnivore
Eats meat
Eats Both
Eats Plants
56

• Black bear
• Panda Bear
• horse
• hawk
• cat
• birds
• man
