Food Chains
SOL 3.5
3rd Grade Science
Presentation by
Elaine Bennett
Producers


Make their own
food
Plants are
Producers

They make their
food from the
SUN, WATER,
and NUTRIENTS
in the soil
Consumers



Can’t make their own food
Need to get food from other animals
or plants
3 types of Consumers



Herbivores
Carnivores
Omnivores
Consumers- Herbivores

Eat only plants

Deer
Cows
Mice


Consumers- Carnivores





Eat other animals (meat)
Known as Predators- catch
and kill their Prey (the animal
that is eaten)
Tigers
Frogs (eat flies)
Sharks
Consumers- Omnivores

Eat both plants and
animals

Humans
Raccoons
Bears
Pigs



Decomposers





Eat dead plants
and animals
Help clean up dead
bodies
Fungi (mushrooms)
Bacteria
Worms
Food Chain
All of these organisms interact to form
a food chain
 Almost always stars with a plant (a
producer)
 An herbivore eats the plant, then a
carnivore eats the herbivore
 Grass
mouse
fox

producer…consumer….consumer
Food Webs
Many animals are involved in Food
Webs.
 More than one consumer eats the
same type of food.
 Consumers also eat many types of
foods.

Food Web Example
-Producer
leaf, grass
-Consumer(herbivore)
caterpiller,cricket,mouse
-Consumer (carnivore)
robin, spider, fox, bear
-Decomposer
fungi, bacteria
*remember, decomposers eat dead animals

Summary
The students learned that all of the
organisms on Earth are connected
through the food chain.
 Humans are even part of it. We eat
plants and animals. If we lived in the
wild, we may become prey to larger
animals (sharks)

Quiz completed
 Don’t forget to visit the cool websites
about the food chain
 Visit the library and find a book about
your favorite animal

What kind of food does it eat?
 Does anything eat that animal?

SOL 3.5

The student will investigate and
understand relationships among
organisms in aquatic and terrestrial
food chains
a. producer, consumer, decomposer
 b. herbivore, carnivore, omnivore
 c. producer, prey
