However, they have points of intersection. Last modified: 2023-12-17 05:12

Light and its penetration are of great importance in the life of reservoirs. The life of plants and organisms depends on it. The further the light penetrates into the water column, the deeper the plants will grow. Lighting depends on various external factors, for example, at sunset, less penetration of light under the layers of water than at noon, in the north, rays will penetrate less than in the south, etc. Last modified: 2023-12-17 05:12
