  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. Consumer (food chain) - Wikipedia

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

    A consumer in a food chain is a living creature that eats organisms from a different population. 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.

  4. Heterotrophic nutrition - Wikipedia

    en.wikipedia.org/wiki/Heterotrophic_nutrition

    All heterotrophs (except blood and gut parasites) have to convert solid food into soluble compounds which are capable of being absorbed (digestion). Then the soluble products of digestion for the organism are being broken down for the release of energy (respiration). All heterotrophs depend on autotrophs for their nutrition. Heterotrophic ...

  5. Food web - Wikipedia

    en.wikipedia.org/wiki/Food_web

    The linkages in a food web illustrate the feeding pathways, such as where heterotrophs obtain organic matter by feeding on autotrophs and other heterotrophs. The food web is a simplified illustration of the various methods of feeding that link an ecosystem into a unified system of exchange.

  6. 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 ...

  7. Zooplankton - Wikipedia

    en.wikipedia.org/wiki/Zooplankton

    The shells are usually made of calcite, but are sometimes made of agglutinated sediment particles or chiton, and (rarely) silica. Most forams are benthic, but about 40 species are planktic. [ 36 ] They are widely researched with well-established fossil records which allow scientists to infer a lot about past environments and climates.

  8. Trophic mutualism - Wikipedia

    en.wikipedia.org/wiki/Trophic_mutualism

    Perhaps one of the most famous discoveries made by Muscatine in the field of trophic mutualism came about 10 years later in another aquatic based system-the relationship between algae and water hydra. [8] This work was significant in establishing the presence of mutualistic relationships in both aquatic and terrestrial environments.
