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?

The resident time would be zero because carbon is released as soon as it is absorbed
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 increase because there will be a buildup of carbon in the atmosphere

The correct answer is:

The resident time will depend on where the organism lives because it might be influenced by cellular respiration.

The resident time of carbon in organisms will vary depending on the specific metabolic processes and environmental conditions of the organism.
