Nutrients (arising from phototrophs or other consumers) provide the inputs for both anabolism and catabolism.
Furthermore, these trade-offs are likely to affect the competition and coexistence between mixotrophs and obligate phototrophs or phagotrophs (Rothhaupt 1996).
When moving from the aquatic to the aerial habitat, phototrophs faced considerable difficulties, among them the limited water supply and the scarcity of soluble minerals, especially P.

Variability in summer ice cover potentially results in variability in the irradiance reaching the lake's phototrophs, and Doran et al.
With oxygen-producing cyanobacteria above them and oxygen-avoiding green sulphur bacteria and fermenters below, the phototrophs form a fine coat over the rocks and slowly, but tenaciously, establish their expanding colonies.
In the field, mixotrophs can compete with heterotrophs for the uptake of food particles and with phototrophs for light and mineral nutrients.
Kd[Lambda] for water in which the majority of the DOC is produced by phytoplankton, sea-ice algae or benthic phototrophs (periphyton and macrophytes) will be underestimated by these equations because this autochthonous DOC is not strongly coloured.
In comparing the anabolic pathways of other autotrophs, which include phototrophs, we observed a universality of this feature of anabolism.
