Green plants can do this, and some bacteria have various ways of doing it, but no animal can. Because of the different effect of the mode of carbon acquisition of C. acidophila on the population growth rates of the two rotifers, we investigated the direct competitive abilities of the two rotifer species under various environmental conditions: purely autotrophic, mixotrophic at two light intensities and purely heterotrophic in the dark.
