1. ENERGY AND LIFE Objective:
Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?

2. ALL LIVING THINGS NEED
Energy
TO SURVIVE

3. is the source of energy for almost all living things
SUNLIGHT
is the source of energy for almost all living things

4. On a Post It note: Write: P = C= D=
Write examples of plants/animals that are producers, consumers, and decomposers.

5. Organisms that use sunlight directly to make food
1. Producers
Organisms that use sunlight directly to make food
They do this by a process called PHOTOSYNTHESIS
Also known as Autotrophs – organisms that can make their own food!

6. PRODUCER EXAMPLES:
Grass, Plants,
Trees Corn

7. Biomass
Producers create Biomass – the mass of matter produced by organisms in an ecosystem.
More Glucose produced = Increase Biomass
Glucose contains potential energy

8. 2. Consumers
Organisms that eat producers or other organisms for energy!
Also known as Heterotrophs – organisms that cannot make their own food and must eat other organisms!

9. There are 4 Types of Consumers:
Herbivores
Carnivores
Omnivores
Scavenger

10. A. Herbivores
Consumer that eats plants

11. B. Carnivores
Consumer that
eats animals (meat).

12. C. Omnivores
A consumer
that eats both
plants and animals.

13. Herbivore Carnivore Omnivore
Shark
Raccoon
Koala
Fox
Deer
Hedgehog
Snake
Chicken
Rabbit
Tiger
Horse
Bear
Rhino

14. D. Scavenger
Feeds on the bodies of
dead animals.

15. 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.

16. Known as NATURE’S RECYCLERS and adds nutrients to the soil!
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!

17. Decomposer Examples:
Bacteria and Fungi

18. Ex. Of producer, consumer, decomposer, and scavenger

20. Predator: Eat Prey Example: A Lion eats a rabbit.
The lion is the predator.

21. Prey: The organism that is eaten
Example:
The Lion (predator)
eats the Rabbit (prey).
The PREY is
the Rabbit

22. Cellular Respiration Also known as Aerobic Cellular Respiration
