Objectives
Describe the energy pathways through the different trophic levels of a food web or energy pyramid.
Explain
how energy transfer between organisms shapes the structure of a communitySlide6
C
– level “0-2”

Classroom Rules
Dress properly -no hats, guys-pants must be pulled up, girls- lets not expose ourselves.
No eating or drinking after 1st period breakfast (complete by 7:25)
Come to order when I have clapped my hands.
Respect each other and the teacher
Use proper language. No sign languageNo hitting/pushing/shovingSlide8

Producers and Consumers
Organisms are classified as either
producers
or
consumers based on how they obtain energy and nutrients.Slide10
Producers (Plants)
Organisms called
autotrophs
or
primary producers capture energy from the sun or from chemicals and store it in the bonds of sugars, making energy available to the rest of the community. Slide11
Consumers
(Animals, Bacteria, & Fungi)
Consumers
are called
heterotrophs and make use of the chemical energy stored by photosynthesis or chemosynthesis in a process called cellular respiration. Slide12
Consumer Types
Most primary consumers, such as deer and grasshoppers, eat plants and are called
herbivores
.
Tertiary consumers eat secondary consumers, and so on. Most
secondary and tertiary consumers kill and eat other animals and are called carnivores.Animals that eat both plant and animal food are called omnivores.Slide13
Herbivores, Carnivores, and OmnivoresSlide14
Detritivores
and Decomposers
Detritivores
, such as millipedes and soil insects, consume detritus—nonliving organic matter including leaf litter, waste products, and the dead bodies of other community members.
Decomposers
, such as fungi and bacteria, break down nonliving matter into simpler parts that can then be taken up and reused by primary producers.Slide15
Detritivores & DecomposersSlide16
Energy and Biomass
An organism’s
trophic level
is its rank in a
feeding hierarchy.
Primary producers (plants) always make up a community’s first trophic level.Primary, secondary, and tertiary consumers make up the second, third, and fourth levels.Slide17

evel Restrictions
The relative amounts of energy and nutrients available at each trophic level put restrictions on a community’s structure. Consequently, there are typically only
three or four trophic levels in any community.”Slide18
Energy Transfer in Communities
Consumers
(animals) take
in food through
predation, herbivory, or parasitism, and
burn it using cellular respiration.But in the process much of the original energy is lost as waste heat.
Due to the loss of energy as heat, only a small fraction of the total amount of energy is past on to the next trophic level. Slide19
Ten Percent Rule
A
general rule of thumb is that each trophic
level
contains just 10% of the energy of
the trophic level below it.Slide20
Numbers
and Biomass in
Communities
T
here are generally fewer organisms at higher trophic levels than at lower
ones. A trophic level’s biomass is the total amount of living tissue it contains (Food).Slide21
