FOOD CHAINS AND FOOD WEBS
For Ms. Musich’s Sixth Grade Class
Energy Roles
ProducerObtains energy through photosynthesis
○ All plants
ConsumerObtains energy by eating plants or animals
○ All animals
DecomposerObtains energy by decomposing the dead
remains of organisms○ Fungi & Bacteria
Producer
All food chains begin with a producer
Producer
1st Level Consumer
A 1st level consumer eats the producerThese consumers are known as herbivores
○ Herbivores are animals that only eat plants
1st Level Consumer
2nd Level Consumer A 2nd level consumer eats the first level
consumerThese consumers could be considered omnivores or
carnivores○ An omnivore is an animal that eats both plants and
animals○ A carnivore is an animal that only eats meat
2nd Level Consumer
3rd Level Consumer
A 3rd level consumer eats a 2nd level consumerThese consumers can be considered
carnivores○ A carnivore is an animal that only eats meat
3rd Level Consumer
Scavengers
A scavenger is an animal that doesn’t hunt for food.
They “scrounge” for food that other animals have killed.Some common examples are crows,
hyenas, vultures and raccoons
Decomposers and Scavengers are VERY important parts of an ecosystem! Why?

Fungi is pretty!

Without Decomposers/Scavengers…
We would be living with a lot of trash…
What Do Food Chains Show Us?
A food chain shows how each organism obtains food.
How nutrients and energy are passed from creature to creature.
An example of a food chain with 3 organisms

For Homework!
Create three separate food chains!
Remember, they must start with a producer!
Each chain must be at least 4 organisms long.
COLORING IS NOT OPTIONAL - YOU MUST.
The Circle of Life!
Food Webs
A food web is just a bunch of food chains put together!

Energy Pyramid
An energy pyramid shows the amount of energy transferred from one level to the next.
