1. Living Things

2. Food Chain
Shows how energy from organisms passes from one organism to another
Shaped like a chain

3. Food Web
A diagram that shows the transfer of energy and food relationships between organisms in an ecosystem
Several food chains put together
Looks like a spider web

4. Food Web What does all this mean?
The leaves passes energy to the cricket
The cricket passes energy to the frog
The frog passes energy to the snake
The snake passes energy to the owl

5. Energy Pyramid
Shows the gaining (and loss) of energy along a food chain.
Why would energy be lost as we move up the pyramid?

6. The Energy Pyramid Producers Bottom level of the pyramid
Many of them get their food from the sun
Example: plants, algae
Consumers
Body of the pyramid
Get their energy from eating other organisms
Example: herbivores, omnivores, carnivores

7. Herbivores, Omnivores, and Carnivores
Eat producers (plants only)
Only on the 2nd level of the pyramid
Get 10% of producer’s energy
Omnivores
Eat producers and herbivores (plants and meat)
On the 2nd or 3rd level of the pyramid
Get 10% of producer’s or herbivore’s energy
Carnivores
eat only herbivores and omnivores (meat only)
On the 3rd or 4th level of the pyramid
Get 10% of herbivore’s or omnivore’s energy

8. What is this? Is it a producer or a consumer?
Where does it get it’s energy from?
producers
What type of consumer is this?
herbivore

9. What is this? Is it a producer or a consumer?
Where does it get it’s energy from?
sun

10. What is this? Is it a producer or a consumer?
Where does it get it’s energy from?
Producers, consumers
What type of consumer is this?
omnivores

11. What is this? Is it a producer or a consumer?
Where does it get it’s energy from?
All consumers
What type of consumer is this?
carnivores

12. Energy Pyramid
**Most energy pyramids do not go any higher up because there is .1% energy so little energy at the top 1% energy 10% energy 100% energy
Tertiary Consumers
Consumers
Secondary Consumers or Carnivores
Primary Consumers or Herbivores
Autotrophs
Producers

13. Niche
If an organism’s habitat is its address, its niche is its occupation
Full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions
The role an organism plays in an ecosystem
