PartA. Ecosystems and Food Webs

  

  I. FOOD CHAINS

 

(1)  Go to http://cserc.org/main/games/buildafoodchain/page1-1.html Build a Food Chain

and do the game’s different levels of difficulty. Then,  answer the questions below:

(2)      Choose the Forest Food Chain http://www.ecokids.ca/pub/eco_info/topics/frogs/chain_reaction/assets/flash/chain_reaction.swf

Drag and drop the images until your food chain is correct. Then answer the questions:

 

            1.     What is the correct order for your food chain?

 

 

 

          2.      What 5 things happen if you take the frog out of the food chain?

  II. FOOD WEBS

 

(1)      Go to http://www.harcourtschool.com/activity/food/food_menu.html

           and choose one of the three food webs. Put the food web together!

 

Consumers – are living things that need producers to be their food (animals and people)

Producers – living things which take the non living matter from the environment (plants)

Decomposers – living things which feed off of dead plants and animals (bacteria, fungi)

 

(2) Using the information in the table above answer the following questions about your food chain:

 

We chose ____________________food chain.

 

             Name a consumer in your food web _______________________________

       

             Name a producer in your food web ________________________________

 

             Name a decomposer in your food web ______________________________

 

(3) Go to http://www.harcourtschool.com/activity/food/food_menu.html and choose one of the food webs. Use the info from parts I and II to put the food web together. (Hint: A top-level carnivore is something that preys on other carnivores and it has no predators.)

 

We chose _______________ food web.

 

Name a consumer in your food web ________________________________

 

Name a producer in your food web ________________________________

 

Name a herbivore in your food web ________________________________

 

Name a carnivore in your food web ________________________________
