Conclusions and Significance By taking up intact amino acids, Sarracenia purpurea can short-circuit the inorganic nitrogen cycle, thus minimizing potential bottlenecks in nitrogen availability that result from the plant's reliance for nitrogen mineralization on a seasonally reconstructed food web operating on infrequent and irregular prey capture.

Diet of contaminated insects harms endangered meat-eating plants. Similarly, there is pronounced spatiotemporal variation in the availability, form, quantity, and proportions of each form of N in bogs in general and in the Sarracenia microecosystem in particular.
