Part I: Ecosystems and Nutrient Cycling

 

Your first assignment is to put together a simple food chain and answer the

questions below.

 

  I. FOOD CHAINS

 

(1)                Go to http://www.ecokidsonline.com/pub/eco_info/topics/

frogs/chain_reaction/index.cfm and click on “play the game” to begin.

 

Answer the questions below:

 

        1.    A person is called a _____________________________________ because they 
     eat meat & vegetables.

2.    Food gives people and animals __________________________________.

 

3.    ________________________ are animals that only eat meat.

 

4.    ________________________ are animals that only eat plants.

 

(2)      Choose the Forest Food Chain.

 

            1.     What animals were in your food chain? Place them in the correct order.

 

          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      

             web:

 

              Name a consumer in your food web ____________________________________

       

              Name a producer in your food web _____________________________________

 

             Name a decomposer in your food web ___________________________________

 

  III. NUTRIENT CYCLING

 

A. Carbon Cycle

 

(1)            Go to http://epa.gov/climatechange/kids/carbon_cycle_version2.html  Click and complete scene 1.
 

(2)           Name 2 places on the earth we find carbon:

 

        1.    __________________________     2.  ________________________________

 

 

(3)     Go to http://www.windows.ucar.edu/tour/link=/earth/Water/co2_cycle.html, read about the carbon cycle and fill in the blanks below:

 

           Plants pull carbon (in the form of carbon dioxide) from the atmosphere to make food, through
           a process called ____________________.

 

           Through food chains animals get ____________ from the plants and other animals they eat.

 

            When plants and animals die and ____________, carbon goes back into the ground.

            Some carbon is buried deep in the ground and forms _________________ ___________.

            When humans burn fossil fuels, ________________ is released back into the atmosphere.

 

            When humans and animals exhale, they release carbon back into the air by a process called
            ______________________________.

           

          

 B.    Nitrogen Cycle
