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.
Because algae is so numerous in the ocean

Yes, Brown algae differs from Red and Green algae because Brown algae is used as a thickener in alot of foods. Red and Green algae are used for most of the time for fish and other underwater animals to eat.
Because their symbiotic algae are photosynthetic and require light and warmth from the sun.
Blue green algae like most plant life require photosynthesis to live. Which means they need light. There is no light in the depths of the ocean bottom. The more light and nutrients, the more algae.
kelp forests
Well red algae needs to photosynthesise to stay alive, so it needs to be within the range of the sun. If it does grow deeper than other algal species it may be because it can detect light better than others.
Seaweed, seagrass, kelp, green algae, red algae and brown algae are six commonly-known ocean plants. Plants, or producers, are vital to the health of ocean ecosystems and serve as a food source to higher organisms.
Marine algae are photosynthetic. At depths below 200m there is very little sunlight which would make photosynthesis extremely difficult.
yes, actually 200 meters :P
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.
yes I sw algae in ocean water. Algae grew on my ocean watered plants during a science expirement
