yes they can absorb blue and black chloroplasts which are the only chloroplasts found deep in the ocean, many fish can't.
I'm not sure if that's true but they can live in great depths because of their ability to harvest light energy.
Red Algae
camouflage and water absorbing.
Because algae is so numerous in the ocean
because it is too cold

Accessory pigments absorb light at different wavelengths than does chlorophyll. This process tends to increase the range of depths at which algae can grow. For example, the reddish accessory pigments called phycobilins are especially good at absorbing the blue light found at great depths in the sea, allowing the algae that contain them to live in deep water. Because accessory pigments reflect different wavelengths of light than does chlorophyll, they give algae a wide range of colors.
The answer to this question is because of the efficiency of different pigments to absorb light of different wavelengths. For example, the pigment in red algae can absorb blue-green light that penetrates to greater depths.
Algae depend on sunlight to carry out photosynthesis. There is not enough sunlight below 200 meters.
phycobilins
Marine algae are photosynthetic. At depths below 200m there is very little sunlight which would make photosynthesis extremely difficult.
Yes, actually. Algae at different depths below sea level have adapted over time to use the available light for cell respiration.
Because their symbiotic algae are photosynthetic and require light and warmth from the sun.
