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.
8. Based on the data in Figures 1 and 2, the researchers should make which of the following conclusions about the overall change in net productivity and biomass over the 200 years studied?
Your Answer is
Correct Answer is F
Explanation
From figure 1, it can be seen that net productivity is generally on the rise;
From figure 2, it can be seen that biomass is also on the rise
