They are not considered truly autotrophic by some biologists because nearly all chrysophytes become facultatively heterotrophic in the absence of adequate light, or in the presence of plentiful dissolved food. More complex models of mixotroph ecophysiology have been developed which allow for multiple feedbacks between heterotrophic and autotrophic processes, can represent additional forms of mixotrophy, such as heterotrophs who steal plastids from their prey, and model multiple nutrients and dissolved organic matter in a realistic way for incorporation in ecosystem models (29, 30).
