This system was developed by Robert H. Whittaker in 1969 and was based on the work done by previous biologists like Carolus Linnaeus. autotrophic or heterotrophic Animal-like: capture or trap food Plant-like: produce food through photosynthesis Fungus-like: external digestion as decomposers or parasites . Cell division and sexual reproduction are similar to the related Spirogyra. The relative importance of autotrophic flagellates, desmids, cyanobacteria, and ciliates as food forDaphnia magna was examined using cohort life tables.
