Food Chains and Food Webs:

We are going to learn a little about food chains and food webs.

1.  Play the following games as a review of last week's work:  

• producer, consumer and decomposer

• herbivore, omnivore and carnivore. 

You should play until you get them all correct. 

Once you have read and understood step # 2 try the food chain game below (don't skip ahead to the game!!)

2.  Food chain game - remember that all food chains must begin with a producer who captures the energy from the sun.  The producer is then eaten by a consumer, who may be eaten by another consumer........  At some point, to make a full circle a decomposer needs to return the nutrients to the producer.

In class today we saw how many food chains in an ecosystem form a food web.

3.  Food Web Game - When you have finished all of the above try this game below that explores a food web in the ocean.  You should click on an organism, read the clue and then decide what level of the web it belongs to.  Then click and drag it to the spot.  All of the circles will not be filled when the game is done.

Try out some other food chains and food webs.  As you build each think about what would happen if one organism disappeared.

Some info about predator prey

Try out this site.    When you start trying see if you can find something wrong with it.  Does it tell you you are wrong when you think you did it correctly?  What's the mistake of the program, not your mistake as it tells you?
