Why does rate of photosynthesis in plants growing under the forest canopy show marked decrease ?
Rate of photosynthesis in plants growing under the forest canopy shows marked decrease because when the light passes through a forest canopy, there is a preferential absorption of blue and red regions of visible lights by the foliage of the trees, thereby reducing the visible light absorption in the plants growing under the forest canopy. Thus, there is a marked decrease in the rate of photosynthesis.
