Question

why are green algae not likely to be found in the deepest strata
of the ocean?

Priyanka Bansal · Accepted Answer

Green alga require sunlight for carrying out photosynthesis Deepest
ocean has a very less amount of sunlight, as green alga lack the
photosynthetic pigment that can absorb shorter wavelength of light
like phycoerythrin, they need longer wavelength of light for which
they have to stay at the surface of ocean
