The sustainability would increase because the lower the biodiversity in an ecosystem, the more likely that ecosystem will be sustainable.
The sustainability would increase because the greater the biodiversity in an ecosystem, the more likely that ecosystem will be sustainable.
The sustainability would decrease because the lower the biodiversity in an ecosystem, the more likely that ecosystem will be sustainable.
The sustainability would decrease because the greater the biodiversity in an ecosystem, the more likely that ecosystem will be sustainable.

Q.
In most bird species, the colors on the feathers of males are bright and the colors on the feathers of the females are duller in comparison. Bright colors on males help them to attract female birds for mating. Dull colors on females help to hide them from predators as they sit on their nests to hatch eggs. Which statement does not correctly explain the variation in color between male and female birds?

Maria’s teacher showed the class these two drawings of birds. These birds are the same species, but they have slightly different features. The teacher asked the students to compare the two birds. Each student hypothesized how a variation might help one bird survive better than the other. Which is not a reasonable explanation of how a feature might help one bird survive longer than the other?

Q.
Jordan researched the five species of wild finches shown below for a science project. He hypothesized that the five species all came from the same ancestor. Through natural selection, different finch populations developed different traits. Which statement identifies a trait that differs for these finch species and explains how the change was caused by natural selection?
