Energy
Models?
–
•
Organisms that make their own food.
Plants, Autotrophs
Organisms that eat (consume) their
energy by eating producers
Primary Consumers, 1o heterotroph,
herbivores
2nd Order Consumer:
–
–
Organisms that eat (consume) their
energy by eating 1o consumers
2o heterotroph, carnivores
Where energy comes from?
All energy comes from the
SUN
Producers go through photosynthesis to
change sun energy into energy they can
use called GLUCOSE
Consumers eat producers, get energy in
form of GLUCOSE , which is broken down
in respiration into a form that we can use.
Energy Flow
IS all the energy that plants make passed
on to their consumers?
– Only 10%
– 90% used by organism (pump sap up tree,
growth of leaves, etc..)
This is true for all organisms!
3 Energy Models
Ecological Pyramid:
– Model that shows how energy flows in a straight
line (what eats what)
Food Chain:
– See Above
Food Web:
– Model that shows all the energy flow within a
ecosystem
