-You are one of a team of scientists studying a newly-discovered planet. You are receiving data from a probe that was landed on the planet by an unmanned mission. Your team is working with the little data you have from the probe to learn as much as you can about the planet's basic characteristics. The figure illustrates data collected by the probe at the same location on the planet during what you suspect are two different seasons (season A and season B). If plants from Earth's temperate deciduous forests could grow on this new planet, during which season(s) would they most likely show the most active growth? What other information would be required to determine probable growth patterns?
