"BIO-RING" = ?
Biodiversity and Biomass
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.
- 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.)
- a.___________________________________ # ____
- b.___________________________________ # ____
- c.___________________________________ # ____
- d.___________________________________ # ____

(Use the back for additional organisms if necessary)
- Which organism is the most numerous in your Bio-ring? ______
- Draw the most numerous organism (#8) on the back of this page.
- How many different kinds of animals did you find in your Bio-ring? ______
- How many different kinds of plants did you find in your Bio-ring? ______
- What was the biggest organism in your Bio-ring? ______
- What was the smallest organism in your Bio-ring? ______
- 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
- How many cm2 are in your Bio-ring? (surface area = 1 r2) __________ cm2?
- How many cm2 are in your teacher selected area? __________ cm2
(Show your work on the back of this page.)
- Approximately how much biomass is in your teacher selected area? _______ grams
- How much is that in pounds? (1kg = 2.2lbs) = _______________ pounds
- 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.
- What two compounds make up most of life's biomass? ___________ and ___________
- What is the energy source for hooking these two compounds together? ___________
- 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
- What do most green plants give off during the day? _________
- What do most green plants give off during the nighttime? __________
- Name any living plant that cannot make its own food. __________
