Heterotrophic

Science / Biology / Heterotrophic: Refers to organisms, such as animals, that depend on preformed organic molecules from the environment (or another organism) as a source of nutrients/energy.

Heterotrophic Algae

Science / Marine Biology / Heterotrophic Algae: Algae that take up organic molecules as a primary source of nutrition MORE

Autotroph

Science / Marine Biology / Autotroph: An organism that synthesizes organic molecules from inorganic starting materials through photosynthesis or chemosynthesis. Autotrophs are ecologically important as primary producers as they ultimately MORE

Mixoplankton

Science / Marine Biology / Mixoplankton: Planktonic organisms that can be classified at several trophic levels. For example, some ciliates can be photosynthetic but also can ingest other plankton and are heterotrophic. MORE

Primary Consumer

Science / Marine Biology / Primary Consumer: A heterotrophic, herbivorous organism that feeds directly on a primary producer. Urchins are a primary consumer as they feed on kelp. See also heterotroph, food chain; compare secondary consumer. MORE

Animalia

Science / Biology / Animalia: Animal Kingdom. Multicellular eukaryotic group characterized by heterotrophic nutritional mode, usually organ and tissue development, and motility sometime during the organisms life history. MORE

Secondary Consumer

Science / Marine Biology / Secondary Consumer: A heterotrophic, carnivorous organism that feeds on a primary consumer. Herring feeding on zooplankton are an example of a secondary consumer. See also food chain, heterotroph, primary consumer. MORE
