DEF: HERBIVORES
Animals that EAT PLANTS for their energy.
Another example of an Herbivore...
HerbivoreChemical Energy in body
Thermal Energy*
Floats Off Into Space
*Animal uses energy to move (lost as friction) or to keep warm (heat goes off into space) – all of that energy is hard to use ever again – ENERGY FLOWS
CARNIVORES!
Well, they are all not dangerous.
ANIMALS that EAT OTHER ANIMALS to obtain energy.

Carnivores
Energy is Flowing through from level to level – most of it is lost as it floats into space.
Only 10% of usable energy flows onto the next level.
Thus, the higher on the pyramid you are…
The less efficient is your eating.
It takes a lot plants to feed the insects and rodents to feed a hawk.
Upper Carnivores
You know what I am talking about.
LIONS, TIGERS, AND BEARS.
Oh My!
Last in the chain – DEF: DECOMPOSERS
They recycle materials
THEY EAT DEAD ORGANISMS to obtain their energy.
Mushrooms Buzzards Oh My!
Ecosystem Pyramid
Consider this choice:
1) You can eat 1 pound of fruits and vegetables or
2) You can eat one pound of hamburger.
CONSIDER: It takes ten or more pounds of vegetables to make that one pound of hamburger.
Haiku
For a cow to live
Thousand pounds of plants must DIE
Vegetarian
Energy Floats Up
Not much left when you eat meat
Many plants must die
Copy and Answer this question and then make a pyramid Haiku.
The ecosystem pyramid has a wide bottom and small top because _______.
HAIKU is 5 – 7 – 5. And/or a bumper
sticker describing why you can help the world if you eat less red meat.
