Red algae needs photosynthesis for food, so why can it go into deeper water than green algae?

Answer 1

Red algae needs light to undergo photosynthesis. More than likely, red algae can absorb different light wavelengths further down the water column, making them more efficient in their self-food production. Also, some red algae species may be capable of chemosynthesis ... which uses chemical intake instead of light to produce its own food supply.

Answer 2

diverse wavelengths (which we comprehend as diverse colours, some seen, some no longer) penetrate to diverse depths in water. pink algae takes super element approximately sunshine available at extra perfect depths... "pink algae comprise chlorophyll as nicely as phycobilins, pink and blue pigments in touch in photosynthesis. The pink pigment is suggested as phycoerythrin and the blue pigment is suggested as phycocyanin. Phycobilins take in the golf green, violet, and blue gentle waves that could penetrate deep water. those pigments enable the pink algae to photosynthesize in deep water with little gentle available."
