Categorizing Animals and Plants
• Color Code the animals and plants
Green= Producer (Produce their own
food)
Example: Shrub
Yellow= Herbivore (Eat producers)
Example: Rabbit
Red= Carnivore (Eat Consumers)
Example: Snake
Categorizing Animals and Plants
• Color Code the animals and plants
Purple= Omnivore (Eat Producers and
Consumers)
Example: Birds
Blue= Detritivores (Eats waste or dead
material)
Example: Vulture
Gray= Decomposer (breaks down
material)
Example: Fungi and some bacteria

Food Web
Energy Flow
• Energy is needed to power life!
• Energy flows through the ecosystem.
Producers
• Organisms that make their own food
without consuming another living
organism are called producers.
• Also known as autotrophs
Producers: Photosynthesis
• Sunlight is the main source of energy
for most ecosystems on Earth.
• Organisms use a process called
photosynthesis to convert sunlight
into energy.
Producers: Photosynthesis
Producers: Chemosynthesis
• Some ecosystems rely on energy
obtained from organisms that store
energy in inorganic chemical
compounds.
• Organisms use a process called
chemosynthesis to convert inorganic
chemical compounds into energy.
Producers: Chemosynthesis
Consumers
• Organisms that cannot make their
own food or energy have to
consume (eat) other organisms. This
organisms are called consumers.
• Also called heterotrophs.
Consumers: Herbivores
• Eat Producers (plants)
Consumers: Carnivores
• Eat consumers (meat)
Consumers: Omnivores
• Eat producers and consumers
(plants and animals)
Consumers: Detritivores
• Eat dead organisms
Consumers: Decomposers
• Eat/break down decomposing
material
Energy Flow
• Energy flows through an ecosystem in
one direction from the sun or
inorganic molecules to producers
(autotrophs) and then to consumers
(heterotrophs).
Food Chain
• Food Chain is a series
of steps in which
organism transfer
energy by eating and
being eaten.
Food Web
• Food Web is all of the feeding
relationships among various organisms
in an ecosystem.
Food Web
• Each step on a food web is a trophic
level.
Ecological Pyramid
• An ecological pyramid is a diagram
that shows the relative amounts of
energy or matter contained at each
trophic level of a food web.
Ecological Pyramid
• Only about 10% of the energy
available within one trophic level is
transferred to organisms at the next
trophic level.
