Question

7. Why is most bioluminescence blue in color?

Answer 1

Answer:

Bioluminescence is light produced by an organism using a chemical reaction. While usually blue in color, because this is the light that travels best through the water, bioluminescence can range from nearly violet to green yellow and very occasionally red.

Explanation: Might be wrong

Answer 2

Answer:

Because the red end of the visible light spectrum is absorbed before reaching the deep sea, most of the light emitted is blue and green. However, there are species that emit red and infrared light, and one genus has been found to emit yellow bioluminescence.

Most of the bioluminescence produced in the ocean is in the form of blue-green light. This is because these colors are shorter wavelengths of light, which can travel through (and thus be seen) in both shallow and deep water.
