Food Chains and
Food Web
Objective:
Can I identify producers, consumers,
scavengers, and decomposers in a food chain
or food web?
1.FOOD CHAINS
NOTES
What do all organisms
need in order to
survive?
Energy!
Food Chain
How energy in food
molecules flows from one
organism to the next
Example Food Chain:
What type of
consumers
are here?
Who will get
the most energy
out of this
food chain?
Food Chain
What type of
decomposer
could we add
to this food
chain to add
nutrients to the
soil?
Which is the
predator?
Which is the
prey?
Reality Check
• Can I identify producers,
consumers, scavengers, and
decomposers in a food chain or
food web?
2. FOOD WEB
NOTES
Food Web
Contains lots of food chains.
Everything is connected and
energy is being transferred
in many ways!!!!!
Example Food Web:
Now paste your notes on page 72

Energy Pyramids
• A diagram that shows
an ecosystem’s loss
of energy.

Reality Check
• Can I identify producers,
consumers, scavengers, and
decomposers in a food chain or
food web?

DRAW YOUR OWN
FOOD CHAIN AND
FOOD WEB
Instructions:
After your cut and paste, turn to page 75
complete the following pictures. You
can title this page Food Chain and
Web Pictures.
1. Draw a Food Chain. You must include
a producer,2 consumers, and
decomposer. Label each and use
color
2. Draw a Food Web. You must include 2
producers, 4 consumers, and 2
decomposers. Label them and use
color
Symbiosis
• Objective:
Can I identify producers, consumers,
scavengers, and decomposers in a
food chain or food web?
Symbiosis
• Relationship where
two organisms live in
close association with
each other.
3 Types:
• Mutualism
• Commensalism
• Parasitism
Mutualism
• Both species benefit.
• Butterfly benefits from
getting nectar.
• How does the flower
benefit from this
relationship?
Mutualism
Commensalism
• One organism
benefits and the other
one in unaffected.
Commensalism
• One of the examples in the ocean is seen in
sedentary crustaceans known as barnacles.
These are very sedentary crustaceans, and so,
they usually attach themselves to a substrate in
the sea like rocks or preferably whales, seat
turtles, etc. When whales and such creatures
travel, the barnacles get access to nutrient rich
waters and often, the morsels of food that are
left behind by the whale, the barnacle catches it
and eats it. These barnacles do the same thing
when they attach themselves to the bodies of
green sea turtles.
Reality Check
• Can I identify producers,
consumers, scavengers, and
decomposers in a food chain or
food web?
Parasitism
• One species, the
parasite, benefits
from the other
species, the host,
which is harmed.
