光适应和光驯化的生态学意义充其量是推论性的。这是由于两个因素：1）多细胞组织的光吸收维度在理论上描述不充分，这受到多色光场与不同捕光色素-蛋白质系统的相互作用、包装效应、非均匀吸收和多重散射的干扰。2)从生理尺度的测量，即光合作用-入射光曲线，推断生长对光利用的实践。所需的是设计成产生光吸收特性（LHPP和组织解剖学的函数）与光利用效率的关系的参数。参数，吸收截面归一化碳（aC）和光子生长产额（PGY），量子产额的增长模拟，在这里演示。
The ecological significance of photoadaptation and photoacclimation is at best inferential. This is attributed to two factors: 1) The dimensions of light absorption by multicellular tissues are inadequately described by theory, which is confounded by the interaction of polychromatic light fields with different light harvesting pigment-protein systems, the package effect, heterogeneous absorption and multiple scatter. 2) The practice of extrapolating light utilization for growth from physiological scale measurements, i.e. photosynthesis-incident light curves. Needed are parameters designed to yield the relation of light absorption properties (a function of LHPPs and tissue anatomy) to light utilization efficiency. The parameters, absorption cross section normalized to carbon (aC) and photon growth yield (PGY), the growth analog of quantum yield, are demonstrated here.
