ENERGY COMES
FROM....
FOOD!
• However, not all
organisms can
eat the same
things. Let’s
watch this
Discovery
Education video
to learn more
about the energy
flow between
organisms.
PRODUCERS
•Producers are organisms that make their own food for
energy.
•Producers are the beginning of a simple food chain.
Producers are plants and vegetables. Plants are at the
beginning of every food chain that involves the Sun.
•All energy comes from the Sun and plants are the ones
who make food with that energy.
•They use the process of photosynthesis. Plants also
make loads of other nutrients for other organisms to eat.
•Examples: Oak Tree, Palm Tree, Grass, Plankton (Plants in
general)
CONSUMERS
•Consumers are organisms that eat other living things
for energy.
•Three different types of consumers: Herbivores are
consumers because they eat plants for energy.
(Examples: Rabbit, Deer, Cows, Kagaroos)
•Carnivores are consumers because they eat other
animals for energy. (Examples: Cheetah, Lion, Tiger,
Venus Fly Trap, Crocodiles, Owls, Snakes, Sharks)
•Omnivores are consumers because they eat both
plants and animals for energy. (Ex: Humans, Bears,
Racoons, Chickens, Some fish)
DECOMPOSERS
•Decomposers are organisms that break down other dead
plants or animals for energy.
•If you die, they eat you. If you poop, they eat that. If you lose a
leaf, they eat it. Whenever something that was alive dies, the
decomposers get it.
• Decomposers break down nutrients in the dead "stuff" and
return it to the soil.
•The producers can then use the nutrients and elements once
it's in the soil.
•The decomposers complete the system, returning essential
molecules to the producers.
•Examples: Mold, some types of worms, fungi, some bacteria,
flies (& maggots), cockroaches, lactobacteria (for your
mozzarella cheese and frozen yoghurt)

WHITE BOARD QUIZ!
1. What would you call a consumer
who eats beef a chicken?
2. What would you call a consumer that
eats leaves, fruits, and nuts?
3. What would you call a consumer who
eats rice and chicken?
4. What would you call the organisms that
cause dead plants and animals to rot
and break down?
DAY 2
ENERGY FLOW
• A food chain shows a direct link
between and animal and the thing it
eats and is eaten by.
• Food chains show how energy flows
between organisms.
