  2. Heterotroph - Wikipedia

    en.wikipedia.org/wiki/Heterotroph

    A heterotroph (/ ˈ h ɛ t ər ə ˌ t r oʊ f,-ˌ t r ɒ f /; [1] [2] from Ancient Greek ἕτερος (héteros) 'other' and τροφή (trophḗ) 'nutrition') is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are ...

  3. Biological carbon fixation - Wikipedia

    en.wikipedia.org/wiki/Biological_carbon_fixation

    Organisms that grow by fixing carbon, such as most plants and algae, are called autotrophs. These include photoautotrophs (which use sunlight) and lithoautotrophs (which use inorganic oxidation ). Heterotrophs , such as animals and fungi , are not capable of carbon fixation but are able to grow by consuming the carbon fixed by autotrophs or ...

  4. Heterotrophic nutrition - Wikipedia

    en.wikipedia.org/wiki/Heterotrophic_nutrition

    Heterotrophic nutrition is a mode of nutrition in which organisms depend upon other organisms for food to survive. They can't make their own food like Green plants. 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.

  5. Myco-heterotrophy - Wikipedia

    en.wikipedia.org/wiki/Myco-heterotrophy

    Monotropa uniflora, an obligate myco-heterotroph known to parasitize fungi belonging to the Russulaceae. [1]Myco-heterotrophy (from Greek μύκης mýkes ' fungus ', ἕτερος héteros ' another ', ' different ' and τροφή trophé ' nutrition ') is a symbiotic relationship between certain kinds of plants and fungi, in which the plant gets all or part of its food from parasitism upon ...

Breaking Chemical Compounds Chemo-Organic-organo-Organic-heterotroph: Chemo organo heterotroph: Predatory, parasitic, and saprophytic prokaryotes. Some eukaryotes (heterotrophic protists, fungi, animals) Carbon dioxide-autotroph: Chemo organo autotroph

  7. Carbon source (biology) - Wikipedia

    en.wikipedia.org/wiki/Carbon_source_(biology)

    A heterotroph (/ ˈ h ɛ t ər ə ˌ t r oʊ f,-ˌ t r ɒ f /; [3] [4] from Ancient Greek ἕτερος (héteros) 'other' and τροφή (trophḗ) 'nutrition') is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter.

  8. Photoheterotroph - Wikipedia

    en.wikipedia.org/wiki/Photoheterotroph

    These waterlogged environments may facilitate symbiotic relationships between heliobacteria and rice plants as fixed nitrogen—from the former—is exchanged for carbon-rich root exudates. Observation studies have characterized photoheterotrophs (e.g., Green non-sulfur bacteria such as Chloroflexi and AAPs) within photosynthetic mats at ...

  9. Consumer (food chain) - Wikipedia

    en.wikipedia.org/wiki/Consumer_(food_chain)

    A consumer is a heterotroph and a producer is an autotroph. Like sea angels, they take in organic moles by consuming other organisms, so they are commonly called consumers. Heterotrophs can be classified by what they usually eat as herbivores, carnivores, omnivores, or decomposers. [1]
