Summary of today’s notes on Consumers
Bell Work:
1. Define the term producer
2. What are the 2 processes that producers can use
to make food?
3. Why are producers vital to every ecosystem?
4. Where would one find a chemosynthetic bacteria?
Examples of good summaries:
- Producers make their own food using
sunlight or chemical energy. Consumers
get energy by eating producers or
consumers. Without producers there
would be no life on earth
OR
- In this unit we will study living things and
their environment. Producers are
organisms that make their own food while
consumers eat other organisms.
Friday we were learning about
feeding relationships.
Let’s review.
Producers
- Organisms that make their
own food by using sunlight
or chemical energy
- Also known as Autotrophs
(self feeders)
- Examples
a. all Plants
b. Blue-green bacteria
c. algae
d. Sulfur bacteria;
hydrothermal vents
How do
producers
make their
own food?
1) Photosynthesis – they
use sun light
OR
2) Chemosynthesis – they
use chemicals
Producers - they make their own food!
Photosynthesis – using
light energy
Chemotroph (using chemical energy)
Consumers
- Consumers obtain energy
from eating producers
and/or other consumers.
- also known as heterotrophs
(other feeders)
- Examples
a. all animals
b. Fungi- mushrooms and
yeasts
c. Some bacteria
These are all consumers
Pair – Share Review
P1: What is another word for a consumer
and what is the definition of a
consumer?
P2: What is another word for a producer
and what is the definition of a producer?
Set up for today’s notes:
Types of Consumers
Unit 1: Ecology
Types of Consumers
Aug. 27
Types of
consumers
1) herbivore
(herb= plant, vore=eat)
- An organism that eats ONLY
producers (plants)
- Some common examples:
cows, sheep, rabbits,
elephants
2) Omnivore
(omni = all)
- Eats BOTH producers and
consumers (plants &
animals)
- Some common examples:
bears, raccoons
3) Carnivore (carne = meat)
- Eats ONLY consumers
(other animals)
- Some common examples:
lion, wolf, eagle
Pair - Share
• Tell your partner what the difference is
between a herbivore, omnivore, and
carnivore.
Chemically
break
down
4) Decomposers
organisms and then use
the new chemicals
- Some examples:
mushrooms, molds, many
types of bacteria
- Recyclers of each
ecosystem!
Look inside your
refrigerator and
find some
decomposers in
action
5) Detritivore
- Eat remains of dead
organisms
- Some examples are
earthworms, vultures,
ravens
California
Condor is a
vulture!
On your own
Silently, review your notes
Pair Share: Ask you partner
Partner 1 ask Partner 2 these questions:
Name the 5 types of consumers and give an
example of each
Partner 2 ask Partner 1
Explain how decomposers are different from
detritivores
1.
2.
Pair Share: Ask you partner
Name the 5 types of
consumers and give
an example of each
Explain how
decomposers are
different from
detritivores.
Herbivore-rabbit, omnivoreraccoon, carnivore- wolf;
decomposer-mold,
detritivore-earthworm
Detritivores feed on dead
stuff while decomposers
chemically break down
organisms or materials
and use the new stuff
