Question

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

Answer 1

The photosynthetic organisms of the water can survive at a depth of 100 meters due to the presence of blue light.

Step-by-step explanation:

There are two colors which are responsible for the process of photosynthesis. These two colors are red and blue. Red and blue light of solar radiation is absorbed and green light is reflected back by the green pigment called chlorophyll. So in the depth of 100 meters in the water, blue light is present so plants can make their own food during photosynthesis.
