  2. 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.

  3. Heterotroph - Wikipedia

    en.wikipedia.org/wiki/Heterotroph

    [3] [4] Living organisms that are heterotrophic include all animals and fungi, some bacteria and protists, [5] and many parasitic plants. The term heterotroph arose in microbiology in 1946 as part of a classification of microorganisms based on their type of nutrition. [6] The term is now used in many fields, such as ecology, in describing the ...

  4. Holozoic nutrition - Wikipedia

    en.wikipedia.org/wiki/Holozoic_nutrition

    Holozoic nutrition (Greek: holo-whole ; zoikos-of animals) is a type of heterotrophic nutrition that is characterized by the internalization and internal processing of liquids or solid food particles. [1]

  5. 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.

  6. Primary nutritional groups - Wikipedia

    en.wikipedia.org/wiki/Primary_nutritional_groups

    Synthetic biology efforts enabled the transformation of the trophic mode of two model microorganisms from heterotrophy to chemoorganoautotrophy: Escherichia coli was genetically engineered and then evolved in the laboratory to use CO 2 as the sole carbon source while using the one-carbon molecule formate as the source of electrons.

  7. Eating - Wikipedia

    en.wikipedia.org/wiki/Eating

    Amandines de Provence, poster by Leonetto Cappiello, 1900, which shows a woman eating almond cookies. Eating (also known as consuming) is the ingestion of food.In biology, this is typically done to provide a heterotrophic organism with energy and nutrients and to allow for growth.

  8. Mixotroph - Wikipedia

    en.wikipedia.org/wiki/Mixotroph

    A mixotroph is an organism that uses a mix of different sources of energy and carbon, instead of having a single trophic mode, on the continuum from complete autotrophy to complete heterotrophy. It is estimated that mixotrophs comprise more than half of all microscopic plankton. [1] There are two types of eukaryotic mixotrophs.

  9. Nutrition - Wikipedia

    en.wikipedia.org/wiki/Nutrition

    Nutrition is the biochemical and physiological process by which an organism uses food to support its life. It provides organisms with nutrients , which can be metabolized to create energy and chemical structures.
