A manufacturing factory is accused of emitting high levels of CO2 into the ecosystem. The factory burns coal to heat steel drums. The factory uses lake water to cool the drums. The water is poured over the drums and then emptied back into the lake Scientist A claims the factory is responsible. The burning of coal releases excess CO2 into the atmosphere. This excess CO2 is transferred to all areas. The CO2 is not lost throughout the system. Scientist B clams the factory is not responsible. The CO2 is released directly into the atmosphere, not into the lake. The CO2 is lost into the upper layers of the atmosphere and not cycled back into the ecosystem The model represents the cycle of carbon in the atmosphere. Which key issue illustrated in the model would best support Scientist A's claim? A) The model shows a factory creating excess levels of CO2
B) The model depicts a continuous cycle. An increased level in one area will
increase levels throughout.
C) The model depicts multiple cycles. The atmospheric cycle would show an
increased level of CO2
D) The model shows high levels of carbon in the lake. Any change to this level
will have a greater impact on the atmosphere.
