Quizplus · Accepted Answer

A microbe that can grow only at the surface of the water is likely to be a phototroph, as it requires access to light for photosynthesis. Heterotrophs, chemotrophs, and lithotrophs can grow at various depths within the water column, while anaerobes do not necessarily require access to the surface.
