Heterotroph - Definition and Examples | Biology Dictionary
2017年4月27日 · A heterotroph is an organism that cannot manufacture its own food by carbon fixation and therefore derives its intake of nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are secondary and tertiary consumers.
Heterotroph - Wikipedia
Heterotrophs represent one of the two mechanisms of nutrition (trophic levels), the other being autotrophs (auto = self, troph = nutrition). Autotrophs use energy from sunlight (photoautotrophs) or oxidation of inorganic compounds (lithoautotrophs) to convert inorganic carbon dioxide to organic carbon compounds and energy to sustain their life.
Heterotroph | Consumers, Nutrition & Metabolism | Britannica
Heterotroph, in ecology, an organism that consumes other organisms in a food chain. In contrast to autotrophs, heterotrophs are unable to produce organic substances from inorganic ones. They must rely on an organic source of carbon that has originated as part of another living organism.
Autotroph vs Heterotroph - Difference and Comparison | Diffen
Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — …
Heterotroph – Definition, Types, Examples, and Differences with …
2023年2月17日 · Heterotrophs occupy the second and third trophic levels in a food chain after the first level consisting of autotrophs. Heterotrophs are primarily classified into four different types based on their food habit and presence in the food chain. They are herbivores, carnivores, omnivores, and detritivores. 1.

2023年10月19日 · Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms.
Heterotroph - Definition and Examples - Biology Online
2023年5月25日 · In biology and ecology, a heterotroph is an organism that does not have the ability to chemically produce (i.e. synthesize) its own food from inorganic molecules. Because of this inability, heterotroph feeds on other forms of life to derive their organic nutritional requirements. (Ref.
