They gather light energy through photosynthesis. autotrophic to heterotrophic ... An amoeba Foraminifera Helizoans. Autotrophs - photosynthesize and create their own food Heterotrophs - consume other organisms Mixotrophs - use a combination of autotrophic and heterotrophic traits Oomycota . Edit My Search | New Search. Euglenoid chloroplasts resemble those of green algae, and are probably derived from the green algae through endosymbiosis. However, because many living Radiolaria contain symbiotic photosynthesising algae they must spend at least daylight hours within the photic zone. moves using flagella supported by microtubules; parasites on vertebrate and invertebrate hosts; lives in blood of rats and transmitted by fleas; T. gambiense. Bacillariophyta. They literally transformed the fate of inorganic and organic carbon in the Earth’s biogeochemical system. Phlyum Zoomastigina.

Which organelle functions to remove excess water? In contrast, cyst assemblages from the Last Glacial Maximum exhibit a relatively low diversity and an increase in the cysts of heterotrophic dinoflagellates, in particular Selenopemphix nephroides. Sometimes reproduce too rapidly and create. Heterotrophic is and organism that gets it's food from something other than it's self, while autotrophic, plants, get their food directly from sunlight. -heterotroph: Photo litho heterotroph: Purple non-sulfur bacteria: Carbon dioxide-autotroph: Photo litho autotroph: Some bacteria (cyanobacteria), some eukaryotes (eukaryotic algae, land plants).
