Directions: Take your wire "Bio-ring" ( 16cm in diameter ) and randomly throw it out in the area selected by your instructor. Do not move your Bio-ring once it has been thrown. Next answer the following questions and problems given below. You may work in teams of two or three.

1. How many different kinds of organisms did you find in your Bio-ring? _____
   List the different organisms found in your Bio-ring.
   Also list the #'s of each kind of organism.
   (Use any nature manuals you can for identification or ask your instructor.)
   
2. a.___________________________________ # ____
   
3. b.___________________________________ # ____
   
4. c.___________________________________ # ____
   
5. d.___________________________________ # ____
   
6. e.___________________________________ # ____
   (Use the back for additional organisms if necessary)
   
7. Which organism is the most numerous in your Bio-ring? ______
   
8. Draw the most numerous organism (#8) on the back of this page.
   
9. How many different kinds of animals did you find in your Bio-ring? ______
   
10. How many different kinds of plants did you find in your Bio-ring? ______
    
11. What was the biggest organism in your Bio-ring? ______
    
12. What was the smallest organism in your Bio-ring? ______
    
13. Approximately how much biomass is in your Bio-ring ? You may take 1/4 of the organisms in your Bio-ring back into the classroom to weight them. Multiply their mass by 4 to get the total surface biomass of your Bio-ring. Once you have the surface biomass of your Bio-ring, double it because you have about an equal amount of bio-mass under the ground. Our total biomass (above & below the surface) in our Bio-ring is: = ___________ grams
    
14. How many cm² are in your Bio-ring? (surface area = 1 r²) __________ cm²?
    
15. How many cm² are in your teacher selected area? __________ cm² (Show your work on the back of this page.)
    
16. Approximately how much biomass is in your teacher selected area? _______ grams
    
17. How much is that in pounds? (1kg = 2.2lbs) = _______________ pounds
    
18. Think of a way in which you could measure the total biomass production of your teacher selected area per day. "Be creative" Use the back of this page.
    
19. What two compounds make up most of life's biomass? ___________ and ___________
    
20. What is the energy source for hooking these two compounds together? ___________
    
21. How could we figure out how much oxygen is produced in the teacher selected area per day? (Use back of this page.) "6CO₂'s + 6H₂O's = C₆H₁₂O₆ + 6O₂'s
    
22. What do most green plants give off during the day? _________
    
23. What do most green plants give off during the nighttime? __________
    
24. Name any living plant that cannot make its own food. __________
    
25. What is the most important food crop in the U.S.A.? _________
