Question: Considering the specific physiological posture displayed by the primary organisms in the foreground, which transformation is this human-managed ecosystem most likely to undergo in the near term?
A. Initiate a nocturnal positive-phototaxis mechanism to prepare for the next light cycle.
B. Its main constituent units will reorient to track the luminous body on the horizon.
