A forest was studied for decades after a fire that destroyed a 45-hectare area. The abundance of three plant species was measured and recorded over the course of this study. Which explanation describes the changes in population size for species I, II, and III over the course of the experiment?
A)Species I requires high light conditions. Species II and II eventually outcompeted species I for light.
B)Species II and III require deeper soil for their root structures to grow, while species I requires no soil to germinate.
C)Species I requires drier conditions that are found after the fire while species II and II require high periods of rainfall.
D)Species I requires pollinators to migrate into the area in order to facilitate its reproduction while species II and III reproduce in the absence of pollinators.
