Which Algae Is Found in Deepest Water?

Explanation: Red algae is mostly likely to be found in deep water. This has to do with the different wavelengths of light and how deep they can penetrate water. Red light has the longest wavelength of the visible spectrum which means it penetrates water the least.

Why is red algae found in deepest water?

The red "algae"

Because blue light penetrates water to a greater depth than light of longer wavelengths, these pigments allow red algae to photosynthesize and live at somewhat greater depths than most other "algae".

Which algae live in deep sea?

The correct answer is red algae. Red algae is just named 'red', because of the pigment it contains - 'phycoerythrin'. This phycobilin/phycoerythrin can absorb the blue light and use it for photosynthesis, thus using the little solar energy that reached the deepest part of the ocean for manufacturing food.
