Question

Refer to the two graphs below. Seedlings ofan annual plant were split into two equal treatment groups; in one group, extra fertil zer was provided, and in the other group (the control group), no additional fertilizer was added. The numbers of seeds and the average welght of the seeds from each indvidual plant were monitored, and these data were plotted (each point represents an indvidual plant). The first graph represents the number of seeds (x-axls) and the welghts of those seeds in micrograms)( y-axis) from the control group. The second graph represents the number of seeds and the weights of those seeds from the group with fertilizer With fetiier 25a 00 203 0 Number of sod 0 0 0 0 0 80 seeds Number of Reference: 7.3 Which statement best describes the results of this study? A. Trade-offs between seed size and seed number existed in both the control and the fertilizer groups, and these trade-offs were of roughly equal magnitude. B. A trace-off between seed size and sced number existed in the control grou C. A trade-off between seed size and seed number existed in the fertilizer group but not in the control group. p but not in the fertilizer group. D. Trade-offs between seed size and seed number existed in both the control and the fertilizer groups, but these trade-offs were much larger in tne fertilizer group.

Explanation / Answer

B.A trade off between size and seed number existed in control group but not in fertilizer group.
