An arctic tundra has a net primary productivity of 100 g m2 yr1 of C. Herbivores in the system ingest 33 g m2 yr of C, but then lose 26 g m2 yr1 of C through egestion and respiration, yielding an actual herbivore productivity of 5 g m2 yr 1. What is the trophic efficiency (as a percentage) for this system? -1 Your Answer: Answer
