Scientists have noted a difference in the concentration of atmospheric gases available to Norway spruce trees at site 1 and site 2. Use Table 1 and Figure 2 to describe the difference in atmospheric gases at each site. Explain how the flow of matter and energy differs in these two locations as a result of the concentration difference. Use evidence from any of the tables or figures to support your answer.
