A THEORETICAL ANALYSIS OF THE EFFECTS OF THREE MIXOTROPH BEHAVIORS ON PLANKTONIC ECOSYSTEMS

Mixotrophy is a common phenomenon in microbial ecosystems and refers to any organism that is both phototrophic and phagotrophic. Despite its widespread occurrence, mixotrophy is frequently overlooked or ignored in planktonic food web models. To accurately represent plankton dynamics, the ecological roles of mixotrophy must be examined and mixotrophs must be incorporated in models. Theoretically, three distinct mixotroph behaviors exist.
