Re: large biomass

Living organisms don't add mass to the planet. They just convert one chemical to another. Plants can't convert light energy into mass, only to chemical energy, which eventually dissipates as heat. Earth is a pretty closed system.
The only mass additions I can think of are meteors and the like.
