Final answer:
To make Francine's carbon cycle model more quantitative, she should include data reflecting the amounts of carbon stored in different reservoirs such as the atmosphere, oceans, and sediments, as well as carbon flux rates.
Step-by-step explanation:
Quantifying the Carbon Cycle:
To build a more quantitative model of the carbon cycle, Francine can add data to represent how much carbon is stored in various reservoirs or sinks. This includes numerical information on carbon quantities in the atmosphere, oceans, ocean sediment, soil, land sediments (including fossil fuels), and the Earth's interior. By adding these details, her model would better reflect the scale of these reservoirs and the dynamics of carbon storage and release. Additionally, integrating carbon flux rates between these reservoirs can enhance the model's accuracy, depicting how carbon moves from one store to another over time.
