"It acquires phototrophy from many different prey species, which means that it actually changes color depending on what it feeds on."
To explore the phenomenon of acquired phototrophy, Moeller, Johnson, Neubert, and Elina Peltomaa, a colleague at the University of Helsinki, took a two-pronged approach.
Relationship Between phototrophy and phagotrophy in the mixotrophic chrysophyte Poteriochromonas malhamensis.
When the zooxanthellae are stressed, the host sponge is not able to capitalize on the energetic benefits associated with phototrophy. To counteract this loss of energy from phototrophy, the sponge can increase its heterotrophic feeding, which is an energetically expensive process itself and therefore may exceed what is energetically feasible.
Many mixotrophs primarily depend on phototrophy as a mode of nutrition (e.g., Caron et al.
