Food Chains and Webs

Let's start with reviewing the parts of a food chain. If you need help, click on the animal.

If you feel comfortable enough

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.

Drag the word to this box to get the answer.

HerbivoresHerbivoresEat Plants Only!

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?

Animals are called consumers.

CarnivoresCarnivoresEat Only Animals!

OmnivoresOmnivoresEat Plants & Animals!

Primary Decomposers

Fungi & Bacteria

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.

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 the eating.

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

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?

1 A diagram with arrows showing energy flow from grass, to a rabbit, to a fox is

A an energy pyramid.B a food chain.C a population chart.D a diagram for football plays.

2 Which of the following is the correct order in a food chain?

A sun a producer adecomposer acarnivoreB decomposer a producer aconsumer a sunC sun a producer a herbivore aomnivoreD sun a herbivore aproducer aomnivore

3 In a food web arrows point in just one direction because they show

A which animal is bigger.B which animals are related.C how energy goes to the animal that is eating.D how energy goes to the animal that is eaten.

4 The arrows on a food chain point to the organism that

A is eaten.B does the eating.C breaks down dead organisms.D returns library books on time.

5 After one species disappears, the other species in the ecosystem

A benefit.B are thrown out of balance.C die.D are unaffected.
