Succession of sessile organisms on experimental plates immersed in Nabeta Bay, Izu Peninsula, Japan*. To compensate for not being able to escape when challenged by unfavorable growth conditions, pests or herbivores, plants have perfected their metabolic plasticity by having developed the capacity for on demand synthesis of a plethora of phytochemicals to specifically respond to the challenges arising during plant ontogeny.
