A scientist counted the average number of plant species found in six plots of land that were each a square kilometer in size. Each
plot was located at a different latitude but a similar elevation. She recorded her results in the table below
Latitude

Which of the following new questions would this data lead to?
OA. What causes different types of plant species to evolve?
OB. How many species of plants grow in high elevation environments?
OC. At what time of the year do most species of plants reproduce?
OD. Why do more plant species live at low latitudes rather than high latitudes?
