Endangered Species Project
You are going to be making an
informational presentation about an
endangered species and its habitat
For next class:
Come up with 3 endangered species that
you would like to work on
Food Chains!
Outline
Trophic levels
Food Chains

Why do we eat?
To gain energy!
Trophic LevelsWho eats what?
Primary Producer
Organisms that produce energy by taking
in sunlight
Through photosynthesis
Mostly plants or other green things
Examples: trees, algae, some bacteria
Consumer
An organism that eats another organism
to get food
There are different types of consumers:
Herbivores
Carnivores
Omnivores
Decomposers
Types of Consumers -
Herbivores
Herbivores eat only plants
Take up the energy produced by plants
Examples: rabbit, caterpillar, koala,
parrotfish
Herbivore Examples
Types of Consumers -
Carnivores
Carnivores eat only meat
Eating other consumers thereby gaining
their energy
Examples: lion, shark, pelican, wolf
Carnivore Examples
Types of Consumers -
Omnivores
Eat both plants and meat
Can take advantage of different food sources
Examples: bears, pigs, humans, raccoons
Omnivore Examples
Types of Consumers -
Decomposer
Organisms that break down dead or
decaying organisms
Decomposers play a SUPER important role
in the ecosystem because they allow for
nutrients and energy to be recycled
Examples: fungi, worms, bacteria
Decomposer Examples
Review – Producer? Consumer?
Decomposer?
Algae = Producer Lion = Consumer
Rabbit = Consumer Mushroom = Decomposer
How are all these creatures
linked together? We can show energy flow from one
organism to the next with food chains
But is it really THAT simple?
Food Webs In any habitat you will have numerous
food chains and these can be linked to
create a food web!
Berries → butterfly → frog → snake → buzzard
Plantain → grasshopper→ frog → snake → buzzard
Berries → chickadee → fox
