Although most diatoms are autotrophic, some heterotrophic or symbiotic species can be found in particular habitats. The living matter of each diatom is enclosed in a shell of silica that it secretes. These shells are marked by minute pores or depressions that allow the living organism access to its environment.iatom (dÄªËÉtÅmË, âtÅmË) [ key ], unicellular organism of the kingdom Protista, characterized by a silica shell of often intricate and beautiful sculpturing.

Examples of Heterotrophs. Not all plants are autotrophic; a few are actually heterotrophic. The European mistletoe is a parasitic plant, surviving off of a host plant. Other plants, such as pitcher plants, are carnivorous and feed on other organisms like insects.You are a heterotroph.hese organisms are called autotrophs. Autotrophs are also called 'self-feeders' and they are able to produce energy from sunlight and carbon dioxide and are therefore known as 'producers.' The only autotrophs that we know of are plants and some types of algae. This makes all other organisms heterotrophs.
