Food Chains and Webs
Let's start with reviewing the parts of a food
chain. If you need help, click on the animal.
producer
consumer
decompser

Plants are called producers.
Why? Because they produce their own food!
How?
They use light energy from
the Sun, carbon dioxide from
the air and water from the
soil to produce food in the
form of glucose/sugar. This
is called photosynthesis.
Back
Animals are called consumers.
Why? Because they cannot make their own food, so they
need to consume (eat) plants and/or animals.
There are 3 groups of consumers.
What does each one eat?
Back
Drag the word to this box to
get the answer.
Herbivores
Eat Plants Only!
Carnivores
Eat Only Animals!
Omnivores
Eat Plants & Animals!
Decomposers
Decomposers
Fungi and bacteria play an important role in the food
chain. They break down dead material and turn them into
nutrients in the soil, which plants use to grow.
Primary Decomposers

With your partner, come up with 3 examples of each.

decomposer
When you have finished your examples, have 1 person from
your group come up and fill in one box.

Creating a food chain.
Remember that a food chain always starts with the sun. The arrows point
to the organism gaining the energy. This means they are doing the eating.
Scroll down, press play and watch how to create a food chain.

Now let's practice creating a food chain
Remember that a food chain always starts with the sun. The arrows
point to the organism gaining the energy. This means they are doing

Now that you have had some practice, lets
try the food chain game. Click on the duck

A food web is several food chains that overlap. Below write 2
food chains that can be found in this food web.

With your partner discuss 2 organisms that would be affected
if the mosquito were removed from this food web. How would
they be affected?
