Aquatic biospheres reliant on oxygenic photosynthesis are expected to play animportant role on Earth-like planets endowed with large-scale oceans insofar ascarbon fixation (i.e., biosynthesis of organic compounds) is concerned. Weinvestigate the properties of aquatic biospheres comprising Earth-like biotafor habitable rocky planets orbiting Sun-like stars and late-type M-dwarfs suchas TRAPPIST-1. In particular, we estimate how these characteristics evolve withthe available flux of photosynthetically active radiation (PAR) and the ambientocean temperature ($T_W$), the latter of which constitutes a key environmentalvariable. We show that many salient properties, such as the depth of thephotosynthesis zone and the net primary productivity (i.e., the effective rateof carbon fixation), are sensitive to PAR flux and $T_W$ and declinesubstantially when the former is decreased or the latter is increased. Weconclude by exploring the implications of our analysis for exoplanets aroundSun-like stars and M-dwarfs.
