Passage V
Seeds from 100 plants of an annual wildflower species were collected and their mass (weight) was determined (Figure 1).
The seeds were divided into 3 groups. One group was planted in pots in a greenhouse. The second group was planted in meadow sites that had been cleared of vegetation. The third group was planted in meadow sites that had not been cleared of vegetation. The resultant plants were dried after flowering. Plants and seeds were weighed separately. Figure 2 shows the mass of the plants.
Figure 3 shows the average mass of seeds produced by the plants.
28. Assume that a 0.9 mg seed of this wildflower species was planted in an uncleared site. What would one most likely observe, according to Figures 2 and 3?
Your Answer is
Correct Answer is F
Explanation
The four options all indicate that plants will grow, so Figure 2 has little effect, but find the value of the curve of the uncleared sites corresponding to the abscissa of 0.9 in Figure 3, and find that it is 0, that is, no seeds will be produced< /p>
