Passage II
Succession refers to the change in species composition in a given area over ecological time.
Table 1 shows the bird species, the dominant (most common) plants, and the successional time in years (yr) on plots of abandoned farmland studied in Georgia.
The estimated changes in net productivity (grams of organic mass produced per square meter per year [g/m2/yr]) and biomass (kilograms of organic material per square meter [kg/m2]) of plants on abandoned farmland in New York appear in Figures 1 and 2, respectively. Successional time is divided into 3 stages based on the dominant plants.
10. Which of the following conclusions about net productivity is consistent with the results shown in Figure 1 ?
Your Answer is
Correct Answer is J
Explanation
As can be seen from figure 1, the vertical coordinate net productivity corresponding to the tree is the largest at this stage
