| Neighboring species | Target species | Effect value |
|---|---|---|
| Virginia spring beauty | star chickweed | 0.4853 |
| Himalayan balsam | marsh woundwort | 0.7905 |
| common dandelion | cat’s ear | −0.6254 |
Researchers Carolina Laura Morales and Anna Traveset gathered data about flowering plants growing alongside each other in various locations. In each case, the researchers identified one plant as a “target species” and a nearby plant as a “neighboring species.” The researchers then calculated a positive or negative value to show how the neighboring species affected pollinator visits to the target species. One example of a neighboring species with a negative effect value is the blank
Which choice most effectively uses data from the table to complete the example?
Explanation
Choice B is the best answer because it most effectively uses data from the table to complete the example of a neighboring species that has a negative effect value. The table lists neighboring species, target species, and effect values. The table shows that only one neighboring species, the common dandelion, has a negative effect value (−0.6254).
Choice A is incorrect because the table shows that the neighboring species Himalayan balsam has a positive effect value, 0.7905, so it isn’t an example of a neighboring species with a negative effect value. Choice C is incorrect because the table shows that star chickweed is a target species, so it isn’t an example of a neighboring species with a negative effect value. Choice D is incorrect because the table shows that the neighboring species Virginia spring beauty has a positive effect value, 0.4853, so it isn’t an example of a neighboring species with a negative effect value.
