resistance of neonates between the three rotifer species. Absorptive heterotrophs eg. An additional 3 fragments from each colony within each set of corals were labelled through their heterotrophic pathway by feeding them 13 C-labeled rotifers (average δ 13 CVPDB=6216‰) for 11 hours at night, then returned to flow-through seawater tanks and one fragment from each colony was collected after 4-, 12-, and 24-hours chase period.

Heterotrophs rely on autotrophs to provide a continuous supply of new organic molecules. (What does it use to move?) They are sexually dimorphic , with the females always being larger than the males. Mixotrophic (autotroph/ heterotroph) e.g. was able to use all C. acidophila with similar efficiency. The induction of those autotrophic and/or heterotrophic communities within aquaculture units can be achieved by manipulating the carbon/nitrogen ratio and light intensity [11, 12]. 0. Both types of communities have been reported to have positive effects on the production response of the farmed shrimp. This cladoceran filter feeds rather unselectively on small particles and can ingest algae, bacteria, ciliates and flagellates (DeMott, 1986; Sanders and Porter, 1990; Jürgens, 1994; Foissner and Berger, 1996) via a variety of pathways.
