Necrophyta (lit. "death plants") are saprotrophic chemophytes.
Necrophytes serve as decomposers, living off the detritus on the ground. As chemotrophs, the hydrogen sulfide given off by organic decomposition serves as an additional food source.
Necrophytes are unique among the chemophytes in that they have forsaken their algae symbiotes. As a result, they do not have red coloration or the capacity for photosynthesis.
