Why do submerged plants receive weaker illumination than exposed floating plants in a lake?
Lake is an inland body of standing water and it is divided into different zones which are defined by the distances from the shore. On the basis of the light penetration, it is divided into two zones: Photic zone (sunlight zone, i.e. illuminated with light) and Aphotic zone (zone where little or no light penetrates). Submerged plants receives less weaker illumination than the exposed floating plants because submerged plants are found below the floating plants where the amount of light is absorbed by the upper layer, i.e. littoral zone (is closest to the shore and are host to various rooted plants and receives sunlight in proper amount for their proper growth).
