Detritivores and saprotrophs are both involved in decomposing the dead biological matter yet there are interesting but slight differences between their methods. Detritivores. Detritivores are a type of heterotrophs that feed on the dead or organic biomass including animals, plants, and faeces. Detritivores are essentially able to digest lumps of biomass separately; hence, most of the unicellular organisms (bacteria and protozoa) and fungi may not fall into the category of detritivores.

Ishtar Terra lies to the north, covering an area approximately the size of Australia, while the Africa-sized Aphrodite Terra lies just south of the equator.
