1. D. rocks and sediment
2. A. Glucose
3. A. Carbon
4. C. Plants take in carbon dioxide from the atmosphere for photosynthesis
5. B. The resident time will depend on where the organism lives because it might be influenced by cellular respiration
1. Which reservoir has the largest deposit of carbon?
A. Atmosphere
B. plant biomass
C. oceans
D. rocks and sediment
2. What do plants use for energy?
A. Glucose
B. Water
C. Fructose
D. Oxygen
3. What do animals such as clams and oysters extract from the water to build their shells?
A. Carbon
B. Silicon
C. Fructose
D. Hydrogen
4. Why does Earth have a lower amount of carbon in the atmosphere than planets such as Venus and Mars
A. Carbon is released into the air during plant decomposition
B. The carbon escapes Earth’s atmosphere faster than it is being absorbed
C. Plants take in carbon dioxide from the atmosphere for photosynthesis
D. Most of Earth’s carbon can be found in the proteins and lipids of organisms
5. If the input and output of carbon is balanced in the carbon cycle, what can be generalized about the resident times of carbon in organisms?
A. The resident time will decrease because plants will be taking in carbon dioxide to use for photosynthesis
B. The resident time will depend on where the organism lives because it might be influenced by cellular respiration
C. The resident time will increase because there will be a buildup of carbon in the atmosphere
D. The resident time would be zero because carbon is released as soon as it is absorbed
