Assuming a prokaryotic mutation rate of 4 × 10 − 7 mutations per gene per DNA replication (86, 87), four simultaneous mutations in every gene shared by the populations of marine heterotrophs (in the upper 200 m), marine autotrophs, soil prokaryotes, or prokaryotes in domestic animals would be expected to occur once every 0.4, 0.5, 3.4, or 170 hr, respectively. ❋ Unknown (2008)
They are obligate autotrophs, so they don't have the enzyme systems to metabolize animal tissues. ❋ Professor In Training (2009)
Protists which have chloroplasts, allowing them to perform photosynthesis thus act as autotrophs, are generally found in the highest concentrations. ❋ Unknown (2009)
Whereas viruses are parasites, and prokaryotes are osmotrophs or autotrophs, marine protist provide examples of these distinct life-styles as well as certain combinations of strategies. ❋ Unknown (2009)
In fact, it probably wasn't even a single organism, but more like a community of organisms, containing autotrophs, heterotrophs, saprotrophs, and phagotrophs. ❋ Unknown (2006)
The very small picoeukaryotes, both autotrophs and heterotrophs, many of which are grazers on bacteria, are extremely diverse but very poorly known. ❋ Unknown (2007)
Plants are independent autotrophs, while animals are parasitic heterotrophs. ❋ Harold McGee (2004)
The core structurally-creative anabolic (energy-storing) network observed in autotrophs supplies the dynamical framework for energy to drive all living organization, as all living systems either are autotrophs or depend on the existence of autotrophs. ❋ Unknown (2010)
The open shelf, the various macrophyte systems, and coral reefs are typically net autotrophs as shown by GPP: R > ❋ Unknown (2010)
"Essentially, what we observed within the phytoplankton (microscopic plants) community was that it switched from a system that was dominated by larger autotrophs (plants that photosynthesise) to a system that was dominated by smaller autotrophs with a lower standing biomass." ❋ Unknown (2010)

Question 1 Organisms which recycle nutrients within ecosystems are primarily known as: A. producers B. consumers C. autotrophs D. scavengers E. decomposers ❋ Unknown (2009)
Chemoosynthetic autotrophs • In come the crabs, clams, and worms that feed on this bacteria ❋ Unknown (2009)
Many sea animals depend upon these microscopic autotrophs as a source of nutrition. ❋ Unknown (2009)
This refers to the set of groups or species that perform different functions in natural systems, at different scales of time and space, e.g., predators of leaf-defoliators, structure-building corals in reefs, decomposers, autotrophs. ❋ Unknown (2009)
