"Man is simply not an animal": an animal is biologically defined as a heterotrophic multicellular eukaryote that lacks cell walls.
Finally, the Chordata are placed with all the other phyla of living creatures that are multicellular and "heterotrophic" (meaning they have to eat), into a "kingdom," Animalia.
A similar amount, about 55 Pg C, is emitted as a result of heterotrophic respiration.
In the sea, autotrophic respiration is thought to account for about 58 Pg of the dissolved inorganic carbon in surface waters each year, with the contribution of heterotrophic respiration being 34 Pg C. Vulcanism
Coliform bacteria was detected in 48% of the beverages and 20% had a heterotrophic plate count greater than 500 cfu/ml.
Usually in surface waters there are about a thousand per ml of small flagellates which feed on bacteria (both autotrophic and heterotrophic prokaryotes) and 1 or 2 ciliates, oligotrichs (Fig 2B) and tintinnids (Fig 2C) or heterotrophic dinoflagellates which feed on autotrophic protists.
Protists which rely on aquiring pre-formed organic matter are heterotrophic.
Work in this area has shown that the microbial food web can comprise a significant fraction of the total community biomass in arctic rivers and lakes, and that energy flow is routed through a diverse trophic network of microbial species displaying a wide array of nutritional modes (heterotrophic bacteria, phototrophic bacteria, phagotrophic protozoa, and mixotrophic flagellates ).
The acidophilic methanotrophs form two new genera: Methylocapsaand Methylocella , the latter affiliating with heterotrophic Beijerinckia indica.
In the time after a fire during which appreciable tree mortality occurred, the majority of respiration shifts from autotrophic to heterotrophic.
