What is a food chain?

Every living thing needs energy in order to live. Every time animals do something (run, jump) they use energy to do so.

All living things and animals get energy from the food they eat.

Plants use sunlight, water and nutrients to get energy (in a process called photosynthesis). Energy is necessary for living beings to grow.

A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. All food chains begin with plant-life (Producers), and end with decomposers.

A simple food chain could start with grass, which is eaten by rabbits. Then the rabbits are eaten by foxes. Then the foxes are eventually eaten by the decomposers. Draw this food chain in your U.o.I. Journal. Put the title ‘Simple food chain’. Make sure you label your drawings, and tell whether each part of it is a producer, consumer or decomposer. Also tell if the consumer is a herbivore, carnivore or omnivore.


You need a head set each.

A good way to figure out a consumer food chain is to work backwards. HOWEVER….You will put in the decomposers at the very end of your food chain.

We can get information from this BrainpopJr site and this one on Food Chains. If you want a challenge, you can check out this Brainpop about the energy pyramid.




  1. Working in groups of 3-4, find pictures of different animals who would be in a specific food chain.
  2. Then, open an A3 document in Pages. Include your photos and add text boxes to tell if it’s a producer/consumer/decomposer and a carnivore/omnivore/herbivore.
  3. Don’t forget to add a title and label all of the group members.
  4. When you are finished, take a screen shot and upload a photo to your blog.
