Question 4
A)Why does Earth have a lower amount of carbon in the atmosphere than planets such as Venus and Mars?(1 point)
Responses
Most of Earth’s carbon can be found in the proteins and lipids of organisms
Most of Earth’s carbon can be found in the proteins and lipids of organisms
The carbon escapes Earth’s atmosphere faster than it is being absorbed
The carbon escapes Earth’s atmosphere faster than it is being absorbed
Plants take in carbon dioxide from the atmosphere for photosynthesis
Plants take in carbon dioxide from the atmosphere for photosynthesis
Carbon is released into the air during plant decomposition
Carbon is released into the air during plant decomposition
Question 5
A)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?(1 point)
Responses
The resident time will depend on where the organism lives because it might be influenced by cellular respiration
The resident time will depend on where the organism lives because it might be influenced by cellular respiration
The resident time will decrease because plants will be taking in carbon dioxide to use for photosynthesis
The resident time will decrease because plants will be taking in carbon dioxide to use for photosynthesis
The resident time would be zero because carbon is released as soon as it is absorbed
The resident time would be zero because carbon is released as soon as it is absorbed
The resident time will increase because there will be a buildup of carbon in the atmosphere
