  2. Algae - Wikipedia

    en.wikipedia.org/wiki/Algae

    Most algae are autotrophic, although some are mixotrophic, ... [10] Some other heterotrophic organisms, such as the apicomplexans, ...

  3. Autotroph - Wikipedia

    en.wikipedia.org/wiki/Autotroph

    Overview of cycle between autotrophs and heterotrophs. Photosynthesis is the main means by which plants, algae and many bacteria produce organic compounds and oxygen from carbon dioxide and water ( green arrow ).

  4. Marine protists - Wikipedia

    en.wikipedia.org/wiki/Marine_protists

    Autotrophic protists that make their own food without needing to consume other organisms, usually by photosynthesis (sometimes by chemosynthesis) Green algae, Pyramimonas: Red and brown algae, diatoms, coccolithophores and some dinoflagellates. Plant-like protists are important components of phytoplankton discussed below. Animal-like

  5. Stream metabolism - Wikipedia

    en.wikipedia.org/wiki/Stream_metabolism

    However, autochthonous (coming from within the ecosystem) pathways also remain important to metabolism in heterotrophic ecosystems. In an autotrophic ecosystem, conversely, primary production (by algae, macrophytes) exceeds respiration, meaning that ecosystem is producing more organic carbon than it is respiring.

  6. Scenedesmus - Wikipedia

    en.wikipedia.org/wiki/Scenedesmus

    Scenedesmus is known to have high biomass productivity among green algae, and has been actively researched for its use for biodiesel production. Its heterotrophic production of biomass and lipid in optimized conditions is reported to have higher efficiency than its autotrophic production.

  7. Dinoflagellate - Wikipedia

    en.wikipedia.org/wiki/Dinoflagellate

    About half of living dinoflagellate species are autotrophs possessing chloroplasts and half are nonphotosynthesising heterotrophs. The peridinin dinoflagellates, named after their peridinin plastids, appear to be ancestral for the dinoflagellate lineage. Almost half of all known species have chloroplasts, which are either the original peridinin ...

  8. Portal:Algae - Wikipedia

    en.wikipedia.org/wiki/Portal:Algae

    Some unicellular species of green algae, many golden algae, euglenids, dinoflagellates, and other algae have become heterotrophs (also called colorless or apochlorotic algae), sometimes parasitic, relying entirely on external energy sources and have limited

  9. Heterotrophic nutrition - Wikipedia

    en.wikipedia.org/wiki/Heterotrophic_nutrition

    Heterotrophic organisms have to take in all the organic substances they need to survive. All animals, certain types of fungi, and non-photosynthesizing plants are heterotrophic. In contrast, green plants, red algae, brown algae, and cyanobacteria are all autotrophs, which use photosynthesis to produce their own
