Object is to earn 100 points or more by building food
chains
Deal out all the cards, the SECOND card dealt to each
player shall be laid face down in front of that player.
This is called “the food chain basis card”. The player to
the left of the dealer begins by asking for a showdown.
Players use showdowns and challenges to acquire cards
and try to build food chains of five or more cards on
their food chain basis card. The chain may be built up or
down or both on the food chain basis card, building on
each card what it eats and what eats it.
▪ For example: if you get MOLE as your basis card you
could build a chain by putting SEED card below it,
then SHREWS-SNAKE-HAWK as the top chain.

Once one player gets a chain of five the
round is over. If the winner can play more
cards to the chain and make a web, they
get any additional energy points for each
card added.

Scoring: Tally up all the energy points for
each completed food chain of 5 cards. Add
energy points for every any additional card
added to a five card food chain.

List of 10 Cards from the Predator game
that you can remember.
Now CIRCLE the ones that made their own
food and UNDERLINE the ones that ate
other animals.
What do we call the circled organisms?
PRODUCERS, AUTOTROPHS

What do we call the underlined ones?
CONSUMERS, HETEROTROPHS

Review Food Chain Vocabulary
Food Web Poster p.2
Food chains show how energy is transferred in an
ecosystem. The arrows show direction of energy flow.
A simple food chain would be the sun grows the grass,
the deer eat the grass, and the wolves eat the deer.
What does the arrow show?
The arrow shows the
ENERGY from
transfer of __________
the sun to the plants, from
the plants to the herbivore
from the herbivore to
carnivore.

A FOOD WEB shows all the feeding relationships in an
ecosystem. The arrows show the transfer of energy.
Requirements:
 Must use all of the organisms on the
cards from the Predator game.
 Arrows connecting the organisms
should follow flow of energy, example, plant to elk.
 Posters should be neat and easy to follow
 Use name of the animal and a quick sketch.
 Put your name on the back of the paper
 Card List: bobcat, raccoon, death & decay, squirrel, snake, shrew,
hawk, owl, plant-eating insects, preying insects, frogs & toads,
spider, millipede, centipede, bird on ground, bird on twig, bird on
leaf, bird on truck, turtle, opossum, earthworm, mole, mice,
ferns, buds & twigs, grass, fungi, bark, fruit, leaves, nuts, herbs,
seed, skunk, bear, rabbit, porcupine, deer, fox.

Using this food web:
 What are the producers?
 What are the consumers?
 What are the herbivores?
 What are the carnivores?

Cell—Basic unit of structure and
function in organisms.
 Some organisms, like bacteria and protists, are
unicellular (made entirely of one cell).
 Some organisms, like fungi, plants, and animals,
are multicellular (made of many cells).

Tissues—Groups of similar cells that work
together to perform a specific function.
 4 major tissue types in animals
▪ Epithelial tissue
▪ Connective tissue
▪ Muscle tissue
▪ Nervous tissue
 Plant tissue
▪ Stem

▪ Root

Organs—structures made of different types of
tissues that work together to perform a
specific function.
 Examples
▪ Heart

same species (kind) that live together in a
particular area at a particular time.
Examples:


All the roses in a rose garden.
All the mushrooms
(of a particular kind) in a
meadow.

Community—All of the populations of
organisms that inhabit the same area at
the same time.
 Examples:
▪ All of the species of grasses,
insects, shrubs, mice, and
bacteria that live in a particular
field.

Ecosystem—All of the communities of
organisms that inhabit an area as well as
all of the nonliving components of the
area that the organisms interact with.
(Communities + Environment).
 Examples:
▪ All of the trees, plants, and animals in a forest plus all of
the water, rocks, air, wind, etc…

all life. All of the environments and organisms
on Earth.

All things in a food web are connected. If one
organism is positively or negatively affected,
then all connected to that organism are also
affected.
If Mountain Lions are completely removed by
hunting, who is affected?
Give an explanation for each organism. Will
they be positively or negatively affected and
explain your reasoning why.
What are trophic levels and energy pyramids?
An energy pyramid is a graphical model of energy flow in a
community through different groups of organisms that might
compose a food chain. From the bottom-up, they are as
follows:
Producers — bring energy from nonliving sources into the
community
Primary consumers — eat the producers, which makes
them herbivores or omnivores
Secondary consumers — eat the primary consumers,
which makes them carnivores or omnivores
Tertiary consumers — eat the secondary consumers
In some food chains, there can be a fourth consumer level,
and rarely, a fifth.
