In water, red light is fully absorbed at about 15 m, orange light is fully absorbed at about 30 m, yellow light is fully absorbed at about 50 m, and blue light is fully absorbed at about 100 m. Based on this information, one can predict that aquatic photosynthetic organisms can survive at a depth of up to almost m
