1. Where does most of the mass that makes up living things (the mighty sequoia tree for example) come from?
A.Oxygen
B.Soil
C.Carbon Dioxide
<u>
D.Water
</u>
2. Which process is responsible for moving carbon from the atmosphere to the producers in an ecosystem?
A. <u>PHOTOSYNTHESIS: where the carbon dioxide (CO2) is turned into glucose (C6H12O6)
</u>
B. CELLULAR RESPIRATION: where the glucose (C6H12O6) is turned into carbon dioxide (CO2)
C. DEFECATION: When an animal poops, carbon goes back into the atmosphere
D. EATING: When animals eat, they take in the carbon from the atmosphere
3. Which process is responsible for moving carbon from a producer/herbivore/carnivore/decomposer back into the atmosphere?
A. PHOTOSYNTHESIS: where the carbon dioxide (CO2) is turned into glucose (C6H12O6)
B. CELLULAR RESPIRATION: where the glucose (C6H12O6) is turned into carbon dioxide (CO2)
<u>
C. DEFECATION: When an animal poops, carbon goes back into the soil
</u>
D. EATING: When animals eat, they take in the carbon from the atmosphere
4. Which of the following are examples of organic carbon?
A. Lipids
B. Carbon Dioxide
<u>
C. Glucose
</u>
D. Both A and C
E. All of the above
5. Which of the following best describes ALL the possible places carbon can go once it is in an acacia tree in the savanna?
**Read carefully, there are correct answers and then there is the BEST answer**
A. The carbon will either go back into the atmosphere by cellular respiration or into an herbivore when they eat the leaves of the acacia tree.
B. The carbon could go into a lion or be used to become part of the acacia tree (biosynthesis)
<u>
C. The carbon would move to the soil where the decomposers would put it back into the atmosphere.
</u>
D. The carbon could go into the atmosphere through cellular respiration, it could become part of the acacia tree (biosynthesis), it could die and move to the soil, or an herbivore could eat the leaves of the acacia tree
