The serial endosymbiosis hypothesis suggests that mitochondria evolved before plastids through a series of endosymbiotic events. . The initial food concentration was above the limiting conditions for rotifer growth: 2.5 mg C L −1 for auto- and mixotrophic algae and 1.9 mg C L −1 for heterotrophic algae (Weithoff, 2005, 2007). That ring upon her finger don't belong to me. Recall that autotrophs make their own food through photosynthesis or chemosynthesis (see the Photosynthesis concepts). Some of these protists are heterotrophic and animal-like: they feed off organic matter and other protists. Social Studies, 21.09.2019 16:30.
