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

In an ocean ecosystem, the biomass of an algal community is approximately 3000 kilograms. It can support a food chain up to 4 levels. Considering an efficiency at an average of 10% in passing on energy from one trophic level to the next level, how much biomass of the fourth trophic level can be maintained.

The average efficiency of energy transfer between trophic levels is 10%. Use this efficiency to determine how much phytoplankton mass is required to add just 1 gram (0.04 ounce) of new mass to a killer whale, which is a third-level or top carnivore. Create a diagram that summarizes the different trophic levels and the relative size and abundance of organisms at each level. How would your answer change if the efficiency were half the average rate? Twice the average rate?
Fertilization & deposition Crop export Watershed Leaching & Runoff Mineralization The figure above shows major N inputs and outputs for a watershed dominated by corn/soybean production. Given an annual change in N storage of 1200 Mg yr for the watershed, calculate the rate of leaching & runoff. To answer this question, assume also the following rates (in Mg yr): fertilization & deposition = 4000; mineralization = 4900; and crop export = 5400. %3! Your Answer: Answer
The position of an organism within a food web is described by its trophic level. When modeling energy dynamics of a food web, losses of energy at these different levels produces a pyramid-shaped distribution of available energy. True or False?
